 done 45 people answering it correctly is good very good very good very good seven no problem dear it will be covered up yeah okay good any explanation required for this question guys second question no no three is i two is j and five is k very good very good let's time here and proceed look at the leaderboard because there are people who have taken 35 seconds to respond which is appreciative i'm not making it a sarcastic remark okay you guys have been reading current responding to this question the fastest nps hsr very good dear okay very good very good i and r fish go one second i need to log into mentee okay dear see it's i'm waiting to proceed for the next question okay yes i i'll tell you like yeah one zero double four six one is the quote one one zero double four six one sir who's james charles jepidia uh no the somebody's name called james charles who is it james charles might be any dear friend of ours you don't know who james charles is sir sir he can continue yeah please thank you very much for the permission no problem and here we go with our next question so eighth question coming for my dear friend who just asked me happy think about it it's displacement change in position displacement is change in position final minus initial while doing that while doing that please keep a proper sequence of subtracting okay in general that's the hint misclick sorry sort of 10 second f raghav raghav is also there 16 second for chirag my dear friend good good good good good good good good so there are people who are seeking time for the okay there will be beautiful questions coming up as well okay there is one particular question where you will also have to use linear equations in two variables so relax boom let's see some people reported very good very good very good very good very good seven and five and two are okay sure for the clarification of it please if a particle moves from if a particle moves from initial position final position suppose then three minus two one everywhere not here four minus three one yes or no everywhere good five minus five zero only at sea got it clear okay everyone very good see for clear where since when we started writing clr that whole comprehensive thingy got it good ashish very good one two and here we go to proceed to the leaderboard again karun very good very good very good very good very good keep it up dear friend and here we go with the next one relax and calculate for dear friend of mine who like like i and our friends okay they said kisa we haven't done it so i'll just repeat if there is a vector a i plus b j plus c k where a b c are its coefficients then its magnitude will be given by square root of a square plus b square plus c square i'll mute everyone then good thank you very much relax so good number of people are still calculating it's beautiful beautiful beautiful square root of a square b square and c square addition a square plus b square plus c square yes for sure you're here you will have to go for the calculation of a b and c as final minus issue so i still haven't got it could you explain it after the sum yeah surely i will be explaining better each and every question so even me yeah very good welcome i'm reading over your charts so relax no problem me too yeah yeah welcome 49 second 51 second people are noting their time that's beautiful quite a tense number of people over here 22 people getting it wrong getting it right sorry next question relax which again final minus initial please please please please please four minus minus two is six minus four minus minus two is minus two and zero minus zero is zero a square 36 plus b square four plus c square square root that is what is called the magnitude of a vector provided the vector is ai plus bj plus ck okay so got it everyone whoever was in confusion got it very good very good very good very good thank you very much let's see the readable and whoa shrijan welcome dear welcome welcome welcome james charles took the shortest interval of time over here very good james charles writing in capitals huh so i guess some dear friend of us only forgot to write their name we can ignore it no problem participating good healthy person right one two and here we go with the next one good good good good good good again relax good now we don't know the relax relax i was aware about this song relax this is to be calculated as magnitude please calculate the magnitude and tell me what it is coming please calculate the magnitude and tell me what is it coming yep magnitude again coefficient of i square plus coefficient of j square the anyway coefficient of k is zero very good nishant very good you remember okay i reminded you sorry vachay namrata if if i have forgot like i really kept things in mind because i haven't kept many questions of vectors very few okay and from the very first day learning what we generally deliver in the class okay but yes i'm sorry i'm sorry i'm sorry somewhere i missed my dear iana batch so i'm really really sorry i'm really feeling guilty about it gandhar beta for that uh if you remember i had shared a good video right over the moxra if you might have witnessed it yep thank you pranav good good good now i was asking one thing over the chart which i was expecting you had to calculate the magnitude magnitude of the vector what is the magnitude of this vector so your answer will be square of the coefficient of i one by two square of coefficient of j one by two add them in a square root you will get one a vector whose magnitude is one is called as a unit vector magnitude zero is called as a null vector vector of a magnitude root two if this would have been a vector of magnitude root two please scalar if this wouldn't be here these things wouldn't be here then it should be considered as a scalar got it no problem so nana beta but yes uh sorry sorry sorry i'm really really guilty about it i'm really guilty about it okay what is the learning out of the last two question guys the learning is if there is a vector of the form a i plus b j plus c k okay where a b and c are numbers then the magnitude of vector a will be given by square root of a square plus b square plus c square okay please remember it relax no problem okay thank you very much thank you very much thank you so if there any sums that i you know that iana isn't going to know could you just like explain the thing to us by default i'll come by default even yes bitter because the magnitude was coming as one so the answer will be unit vector unit is one okay so thank you very much and here we will be having a shuffle good good good very good very good very good thank you very much nishant for bringing my moral up thank you very much nishant thanks a lot we are proceeding to the next question relax think about it you can get it if by now you have got the sense of what vectors are you should get this question if not anyway i'll be explaining it pause the time it's over or concluded finger crossed then i have responded so is the angle in radians bitter you will not need the angle but yes 2 pi by 3 stands for 120 degree where pi stands for 180 okay so by stating this line i have almost declared what answer should be bitter we use this word direction sense in the beginning chapter i'll show you the real question there it was written direction i erased it and stated sense because somewhere i heard it as sense you might hate me for this okay so again here two vectors will cancel each other if they are equal in magnitude and opposite in direction okay so you should have given the hint a little earlier oh no i wanted to but somewhere i got engaged in your chats and all somewhere got it someone in chat but that the answer is okay relax they might have got misguided by what i said right angle will not be required it just states that you will not need the help of b a b c should be the answer and look here you have played tug of war right yes or no then you know this no problem no problem or may i proceed guys please before proceed thank you very much thank you very much next question before that a beautiful and well shuffled and readable yeah nishant is the one responding to this very quickly very good nishant very good and here we go with the next one relax unit vector you know what is a unit vector you know how to calculate the magnitude now you will have to equate it just helping you out you know what is the unit vector okay you know how to calculate the magnitude of a vector you will have to apply the relativity between them and get the correct answer very well tanya what happened bache so even i'm still confused can you explain it again after the question i'll shortly let's discuss in between only meanwhile we'll be helping our other friends as well if you can see on the board whether there's a vector given yes or no right fine now this vector is required to be unit vector okay you don't have to unmute if you want you can keep if you don't want you can put it yourself over mute okay so fine now it has to be a unit vector that means the total magnitude of this vector should be one y or n exactly right now how will you calculate the total magnitude you will square 0.4 you will get 0.16 you will square 0.8 you will get 0.64 you will square c you will get c square in order to make it a unit one c square should be equal to 20 yep beautiful 21 people only responding it correct so the designer of the question succeeded see guys a b and c are available you know the magnitude will be calculated as square root of a square b square and c square you don't know what is c okay so this should be equal to one in order to make this a unit vector okay so squaring on both the side you will get c square is equal to one minus 0.80 so c is equal to square root one minus 0.80 is 0.20 okay relax okay good good good good good good relax relax good one and here we go toward the leaderboard good good good good good good okay yeah please relax no problem see there's a vector which a a b and c a i plus b j plus c k okay this is required to be a unit vector what is a unit vector we learned in the prior questions a vector with magnitude one okay so the magnitude of this vector should be one how will we calculate the magnitude of a given vector we should calculate the magnitude of a bigger given vector by a square plus b square plus c square okay this is a linear equation in one variable for now okay and attempting it we got c should be equal to square root two zero which is square root zero point two okay square root zero point two zero sorry okay got it so thank you very much no problem dear so i will better now i have triggered up the next question okay i'll go back and we'll surely do that no problem now this has been covered everywhere i have had discussion with Rohit and our okay so so equations of motion are have been covered they have been covered everywhere you will have to apply equations of motion relax if you don't get it we will be anyway solving these questions learning out of them okay now the beauty is like most of you are actually solving the question now the beauty so i understood that i was really making a mistake while selecting the questions for vectors because at the time of having vectors on screen you guys were not able to concentrate good very good very good very good it's really good when you concentrate on questions very good very good very good very good think about the third equation of motion think about the third equation of motion beautiful beautiful still we have the highest bar of the correct responders very good very good very good relax come here now a bullet moving with a velocity of 200 centimeter penetrates a wooden block and comes to rest okay what is being related related is s and v in which equation you have the relation of s and final velocity quickly select the equation one two or three third beta in second equation you have s and u in first equation you don't have s right third equation very good so you will write okay in case one it is coming to rest implies that v square is equal to u square okay so plus two a is not known s is known as four centimeters as both are centimeters there is no requirement to interchange or bring the units into s i system okay so good good good good good fine okay good now in what velocity is needed for traveling a distance of nine okay final velocity k square is equals to initial velocity we don't know okay plus two in the same block means the resistance provided by the block is going to be the same and the distance required to be traveled is nine okay fine clear if you will check this you have minus two a four equal to 200 square minus two a nine equal to u square can you please solve out this equation everyone right very good got the answer got the answer g i got it g i a is not at all required region very good when you calculated a but a is not required so we'll eliminate it a right very good very good very good very good very good very good very good okay someone asked me about the previous question as well guys here who was that can you unmute and here or over the chart as well no problem okay so my dear friend this is a vector with its individual coefficients as coefficient of i is 0.4 coefficient of j is 0.8 and coefficient of k c this vector is required to be a unit vector a vector which has to be a unit vector should have its magnitude equal to one so we will calculate its its magnitude and put it equal to one how we calculate the magnitude of a vector we calculate the magnitude of a vector by squaring and adding its individual coefficients by solving this linear equation one variable you will get c is equal to square root 0.2 i hope it helped okay dear friend thank you very much next and before that let's look if the leaderboard is going good shijan gosh is still leading the show very good shijan very good very good very good and even responding to this the fastest a beautiful lead of 400 points from the very next competitor very good very good very good relax and solve relax read and solve please put your microphone over mute dear friend yep read the word precisely you will get the answer reading the question carefully is giving you an easy answer what is being asked average velocity so you will have to look for distance traveled or displacement right this i kept in center so that i can have a good shuffle in between so why do you tell it when the question is still going on better it was midway enough relax then you could have told us earlier no then i know that because who have responded i have to counteract against them right okay i'll stop it i'll not i'll not do in between okay see beauty but it was displacement look into the question a car on a straight road in two hours and then return back that means very good very good guys okay relax please read it think about it there these are certain things which are very well deliberately delivered when we are discussing the class right good very good thank you very much guys moving on to the next one and before that the leader board oh sujan nishant reshap very good reshap taking a leap current very good very good jagrav aroshi anuya are maintaining a tight competition among themselves very good very healthy and here we go toward the next question very good very good better that you can see on your screen if you are not able to see no problem there are 15 questions okay again be careful please be careful please be careful what is this conversation what do you mean by b o t sir a robot okay so like so like is it possible with the at least like i have heard this story from you i don't want to participate in this conversation please guys close it for life now please close it for life please close this story for life very good someone took a lot of time and took is sure about the answer so was that helpful dear taking a lot of time but yeah what happened where have you made the mistake let me do the clarification here okay no problem i'll let's not because we are running by now good with time okay we are running really good with time so let's not go in vain okay keep it centaur let's not make it centaur 1.2 hour 1.3 hour and all sir how many questions five more beta 15 questions i have kept by the total distance covered is sir can you explain the question the total time taken will be speed is equal to distance upon time so time is equal to distance upon speed so it is five seconds but what is ours is average velocity oops average velocity is equal to why it's happening like this why am i not able to write properly sorry average velocity is equal to total displacement upon total displacement is just 25 upon total time five meter per second gi got it i misclicked twice karun no problem dear no problem no problem relax please read the questions that will be helping you out very good very good you guys are learning that's pretty satisfactory on that line but yes no problem let's see the shrijan thola sir took time this time but anyway he was having a good lead so might not be influencing the top positions but yes very good jagra jumping a bit big leap ragha responding to this particular question the fastest very good very good very good and here we go to the next question again patiently solve read it calculate and solve please please i'd be happy if for 30 seconds no one will respond people are responding i don't know how no problem aditya i hope you know the answer i'm calculating it okay keep it with you to tally it with the last conclusion sir you put v for speed i'm having paranoia now like why was there no that's why in order to remove the confusion i kept it as capital so that like people will look for it is kind of confusing huh bitter that is why that's why i said that i will be really happy if i'll not see 30 second because this is so confusing that if you will go halfway and then come back right it happened right yes don't guess jagra at least like in physics and all don't guess relax solve if you want to guess like okay i said you know that you guess is also it gives you a negative kind of motivation when you guess and get it correct you know so i am not a very guttual person right moving to the question actual question 24 people making it correct is beautiful having a parallel column for mistake was also okay to look at because that's a common thing to make mistake in okay so at least the procedure was clear so what you guys do calculate total distance covered upon total time taken y or n because it's about the speed yep for very obvious reasons total distance covered is in three equal parts so is s right but the time taken with different velocities will be different so time one time is equal to distance upon speed so distance upon speed for part one distance upon speed for part two distance upon speed for part three gi got it or d for doubt welcome very good very good very good very good very good very good so take it common cancel it right or not three will also go in the numerator so and v will also go in the numerator no doubt say n d d for doubt to tanya tanya beta unmute and talk to me give a step uh this one this this this part these three times yeah okay see there uh this is the velocity for first one by third distance okay yes for the three equal distances bache the velocities were different yes or no yes that means in these three parts the time consumed might be different only right or not yes that means in order to know the total consumed time we'll have to individually calculate them and add them right yes how we individually calculate the speed time and distance for a non accelerated case speed is equals to distance upon time yes or no so yeah i don't know time is equals to distance actually upon speed in this case distance is being indicated by s so first distance and its velocity second distance and its velocity third distance and its velocity got it bache oh okay got it yeah very good now mathematically we have taken s common cancel the numerator denominator three v from the denominator is common and been sent up we have one by v okay sure so one one by one by three if you will calculate you will get the answer denominator is six yes or no sure plus three plus two okay numerator is three into two which came from the denominator and already there was a three so it is 18 v by 11 charlie gi what is this y e et and all now just just yes yes relax you guys remember this y or n this is the case when just if i'll ask a name prathik r and r 9 can you beta unmute yes dear this formula is used in which case when there are two speeds given two speeds given for what for two equal distances right or not yes yeah so general formula is total displacement upon total time or total essence of open total time but it can in general be given as a distance a journey covered in two equal distances or two equal time intervals right or not if it is two equal time interval it's directly mean of the two speeds yes or no if it is two equal distances then it is two v1 v2 upon v1 plus v2 right yes now this case was of three equal distances okay just giving you an idea your formula is three v1 v2 v3 upon v1 v2 plus v2 v3 plus v3 v1 gi yeah dear we we'll cover it don't worry sorry can you make for four suppose four such things are given then four v1 v2 v3 v4 upon v1 v2 v3 234 341 412 got it yep quickly very good very good very good here we go with the next question and before that a quick glance at the leaderboard whoo whoo jagrav is competing well with our dear friend shijan still maintaining a good place jagrav very congratulations to respond fastest very good very good very good and here we go with the next question quickly read it you will be able to do it very quickly read it you will be able to do it very quickly reading is the only time consuming exercise in this cushion easy got it sir is there a trap or something uh depend on what you have answered yes there is a trap i have kept a trap which might confuse you a little yeah the reading is the only time consuming thing over here throw very good you like you spent time in reading it it's the respect of the cushion what is this bachey pranav if you can like decode it for me is it a message hidden message for me copy paste of what like you can't copy the questions from the screen don't tell me that some of you are attempting it to google and all that you hardly related and at least my shuffle of options so you are not going to get it if you want you can attempt it as well but congratulations but here displacement displacement was the hint two statement about the same thingy one has to be wrong yes or no so now if you'll read it a particle is constrained to move on a straight line path returns to the starting point so displacement is zero this is correct implies that that will be wrong see yes or no throw everyone gee i got it no explanation required okay very good got it very good very very good need a boat quick glance just two questions guys uh yes before nine five we'll conclude next time we'll also start sharp at 800 right or not i'll send you the code of minty in the lingon right better very good very good suggestion raghav is the fastest one to respond it's beautiful to look at it very good very good very good and here you go with the next question 104461 is the code by now uh yes no i am talking about the next meeting the correct statement from the following is again quickly misclicked again look here by a body having zero velocity will not necessarily have zero acceleration why because it might be starting no at the time of starting the acceleration is there the velocity is zero a gi or not right all other things are bluntly wrong right any d for anyone having doubt b but a body having zero velocity will necessarily have zero this word necessarily is wrong because that contradicts with our first statement sir but uh it it has to have zero acceleration right no but it is see you look at it it is at zero velocity and it is starting so it will be having starting acceleration which so in the very next instant of time it will gain some speed with the help of the acceleration given right yes but it very good next question and before that a beautiful leader board good good jagra was the fastest one to respond to it beautiful and here we go with the only lengthy question of the scenario you will have to invest time relax read and see i have given you time for this please it will need time think about it tanya surrendered relax read it you will get it tanya relax bacha please don't lose it metia no how come very good but it's easy but lengthy you will have to think about it the calculation part will end on you very good you even verified it it's very good very good very good no not at all but guys say you surrender when you attempt you have not quit the question you've surrendered here relax as of now the like it's not working i should have kept this question as one of the first very few questions so that you guys can regain the confidence back and come in pace but yes i thought he let's talk about vectors where i went wrong today i was i really miss that i i haven't completed it with my dear i and our friends i'm sorry sorry guys i'm really sorry better because it will need actually it will need time shijan have you responded post 161 seconds okay dear anyway bacha aditya surely i'm i'm like repeatedly i want to apologize for it like yeah shijan but anyway you invested time i have provided you time for that i don't want you guys to see it which is the wrong right one okay okay so relax relax relax a particle travels relax i have i i i know it very good very good very good very good very good congratulations good good good good good good good good a particle travels 10 meter in first five seconds right or not time and displacement will be related in question like equation number two so s is equal to we don't talk about its initial velocity u t plus half a is not known and t square am i clear till here see for clear d for doubt now 10 meter in next three seconds so in this total span of eight second this body has covered 20 meters y or n ashish no problem we will re-discuss about this again i have discussed about how to select the one of the three equations but we'll re-discuss about it personally also welcome so 20 is equal to again so u t plus half a t square y or n y or n y or n you who so in that case can you please calculate for me the values of a and u right now no boom i got like i have embarrassed myself like for not thinking about i r r n r like i n r champions like i'm not feeling very good about it like i'm not feeling anyway positive about it so that's why no boom sound today now yeah quickly what is you and what is a you know these things right you want me to solve no so it will be 20 in the like first equation okay is equal to five u plus 25 a and second equation 40 is equal to 16 u plus 64 a y or n x x sunaina sunaina sunaina dear what happened you can unmute and ask what you explain that 40 part 40 but i see this two no by taking lcm this two went over here oh okay yeah okay no problem now we can go for any method elimination substitution and all right so we'll go for elimination i'll multiply numerator okay yeah fine have i done a mistake no one just uh asked me 10 all right there's two right two five ten sir shouldn't it be eight u like in the second equation two eights are 16 right and 20 what is the problem there was a problem in the first equation where you did not interfere there's no problem in the second equation and you're interfering got it yep good good good good good good good good good good good good good so now 16 and 10 clear i'll multiply the whole first equation by eight i'll multiply the whole second equation by five okay sure clear that is why i had given you those many seconds for this question oh sorry shrijan i i missed your suggestions over the chat so the first equation becomes eight twos are 16 80 u plus 200 a second equation is 200 is equal to 80 u plus yes or no clear 320 a if you subtract 80 u 80 u gets cancelled you have 120 a is equal to quickly 140 right only 40 or 140 sir i got it relax relax relax uh sir i have a doubt how do you get the 160 thing better eight getting multiplied on both the side now we cannot multiply one linear equation only at one side by a number okay yep so so eight twos are 160 right or not eight tens 80 eight 25 200 okay similar 5 4 200 5 16 80 5 64 320 okay good good good good good good good so from here you got a is equal to 1 by 3 okay using this value in any of the equations i'll go by this if i have to then 20 is equal to 10 u plus 25 by 3 you will get the value of u yep 60 minus 25 20 minus 25 by 3 is equals to 10 u gives you 60 minus 25 that is 35 by 3 is equal to 10 u from here you got u equal to 5 twos 7 by 6 y or n y or n y or n units the survey is here okay i haven't seen the participants list good come you got you and a okay okay congratulations you got you and a y or n everyone yep good fine with the help of you and a you have to calculate the total displacement covered in 5 3 and 2 10 seconds okay s is equal to u t plus half a t square okay so here you will get the value of s okay that you have to subtract from the total displacement already done so what are you getting as s quickly please so 170 170 by 3 twos are and 6 yes or no minus 20 already so you get this answer as 50 by 6 which is 68 is a 48.34 okay okay okay sure good good good good good yeah i was aware about the scenario that's why calculating it i was thinking that i'll be saving a lot of time in the initial question so this will consume out a good duration of time sorry for wrong estimation okay clear so here is your answer 16 okay okay come one two and next let's see who wow wow wow wow wow wow very good i guess jagrav is leading the show now no shrijan is very good karan also got a good up yeah karan you missed two three questions in between very good and here we are moving toward the last question think about and respond you will have to think about and respond to no calculation required question i've already given my mother signal ki mama i want to have some food i hope you might also be getting that hurry up sorry for estimating for a closure at 9 and concluding at 9 17 plus 118 at least or 20 actually 19 919 i will be concluding kind of that time but thank you very much for patiently listening to me again i am apologizing for the iana stuff which happened at the beginning sorry dear iana champions it's really really sorry okay uh by next uh we will be coming up but no it's still one type of questions from motion are done like are not done we have to discuss about the graphs okay first we'll do graphs first we'll do graphs and then we'll come to vectors okay so that doing the graphs will give us a good and bandwidth of okay so can you show the leader what yes we will i can see i can this why like i can identify the voice and shrijan jagraf karan aroshi having a tight competition wow shrijan responding to this fastest well played champ good good good good good good very good very good jagra very good karan very good aroshi very good to all the odd 60 people who participated well in patient sorry for the mistake i did for ian r people and thank you very much for patiently listening to me quick respond learning 125 learning outcome 125 quickly one being the smallest five being the highest learning outcome 125 quickly learning outcome 125 learning outcome 125 quickly 125 thank you very much thank you very much good good good good critically pronounced for good thank you very much thank you so thank you thank you thank you thank you sir thank you bye bye bye bye bye thank you sir thank you dear thank you bye bye good night good night good night enjoy the sunday keep your eyes relaxed stay away from the screen you have spent a good screen time this week please stay away from the screen yeah so bye bye bye bye thank you very much good night thank you thank you thank you bye bye bye bye bye biryani waiting for for me or shrijan like vegetarian there's nothing existing like veg biryani right
