 The question was very simple. Suppose there is a building of height 256 meter fine. So, there is this building The height is 256 meter fine. You toss a coin up with some speed. Okay. No problem So, there is a coin which is tossed with some speed say for example you Okay, from the depths This coin lands on the ground in 10 times the time taken by it to reach maximum height fine Time taken to reach maximum height Multiplied by 10 is the time taken to reach on the ground Yeah So What about Fine now What will be the time taken to reach? Understand this what will be the time taken to reach the maximum height? please V is equals to view plus AT I mean am I clear? I am naming time maximum height as T. So This implies that Time taken to reach the maximum height is Yeah So view by G fine now What is the time taken by the same? to reach the ground There are two ways you can calculate this time of the whole journey like this Or you can calculate the time of this journey because displacement is going to be the same So what I am writing this T ground only T Landing I'll write okay instead of writing ground. I'll use landing because G may confuse you with this So I'm just writing T landing. Okay, so s is equal to UT Minus why because this displacement is done in this direction. Whereas in each and velocities in this direction Plus half G Again TL square No doubt fine Cool. What has been provided to you is what has been provided to you is that Please this TL is 10 times TH So can't I write the same equation as 256? equal to minus you 10 TH okay plus half G Again 10 H square No doubt fine Also on the very same line, I can also write TH is equal to U by G because you are Aware with the value of G is equal to here. So instead of TH I'll writing U minus U Again U by G G and 10 got cancelled so U square in doubt plus half G 100 TH U square by G square clear shop No doubt What cancelled 5 Clear or not? Now if you look very carefully here Okay, I'm just creating an extra space for me 5 U square minus U square is 4 U square is equals to 256 Am I clear? So Have I done anything wrong? No Fine S is equals to UT plus half AT square. This half was here G is here here so now U square is 256 by 4 Clear? So that is 16 by 2 is equals to U that is 8 meter Simple shop Here with what speed have you tossed it? You tossed it with 8 meter per second 8 So this question could have been in the end If you would have taken this path to calculate the total time Oh no, you applied the concept of displays on it Because either it goes this way or this way the displays can be the same Fine. See you tomorrow. Have a good day
