 Should do some math about how much force that it Since it is mad. Yeah, we could do it, right? Let's do a project. Yeah, that brought that one was good, too The force of an asteroid that be that big hitting that is yeah That one asteroid the size of a car took out a bunch of buildings in Siberia and it only exploded in the air Yeah, I heard the stuff some of the asteroids that they go It the the impact radius is much larger, right the day after tomorrow I sage one Oh, is that the I sage one? I like that one, too. That was good Helping in math problems here. Yeah for sure Lester. I Can get you some info about it. Sure. Sure from what we know it's Need the weight of it. Can add a momentum is MV Envy Sun super flaring into yeah sunspot activity is going up, but I've also heard that we're going into a nice age, right? Lester for sure you got math questions. Let us know what we do. I Should have my physics formula sheets here really Yeah, Envy mass velocity But it says the asteroid which is set to have a diameter of about 3,250 feet trigger a nuclear winter if it collides with earth The news that well we'd have to know what the we're over to for an ice age according to the problem. Yeah we could do How much does it? It's 3,250 feet You know what can we convert that to meters? That'd be like a thousand meters. That's approximately a thousand meters We could do the conversion but 3,000 3,200 yeah, that's about a thousand meters a thousand Thousand meters right so that's about a thousand meters Just use one kilometer close enough one kilometer Well, if it's one kilometer we would have to know what the density of the the thing is right because if it's an asteroid full of Pumice will be because promise is like volcanic rock. It's very light if it's asteroid full of Basaltic rock or Scott heavy metals in it It the impact will be a lot more than momentum if only someone here knew something about rocks I'm not geology. I do But I forgot it all right, so it's got a diameter. So let's assume is this It's a diameter is one kilometer right one kilometer So this is 500 meters How much does a 500 meter a radius asteroid way? We got to do search. We have to do we have to find out You know what was it density? Oh God, I haven't done a density conversion forever density conversion density Or we could just do a multiple figure out how much uh No, I wouldn't want I don't want to do a density conversion. I haven't done a density conversion for like 20 years Let's see how much how much does a Boulder one meter Yeah Way to come on back to go you can do it You can do it. Let's check it out. I don't know what this thing is giving me Let me check the chat anyone find Cm Cs and m class asteroid is Grams per centimeter cube. Okay, so let's check this out grams per centimeter cube. Okay, so let's do let's do both Let's do the Extremes so let's do here. Let me bring up. There's a wiki paste standard asteroid physical characteristics Look, okay. Cool. So let's do this. So this is our asteroid. Okay. I'm gonna move this over So we're gonna need some space here So let's do some mathematics nice So our question is there's an asteroid coming to the earth, right? And it has a radius of 500 meters Okay, it's traveling at I believe 35,000 kilometers per hour. Was that what it was? Let's take a look at this 35,000 miles per hour. Let's say kilometers per hour Quick calc and head says heavy So let's assume is going at Actually, let's do a conversion 35,000 miles per hour. Let's just do a straight-up conversion Kilometers Kilometers to miles So let's do a little search 35,000 So it's 56,000 kilometers per hour That's pretty fast. Is that how fast is going? That's really fast. Are we sure about that? I Keep seeing 35 to 36. I'm not sure which is right Either way 35 36 That seems really fast 56,000 kilometers per hour. Okay, let's do it Would you submit to have terminal velocity? Yeah, like but terminal velocity only matters Through atmosphere in space you can go. There's no resistance, right? There is no terminal velocity and if astro is going that fast It's just gonna come down and go right. It's gonna part the Atmosphere really like going through is just gonna go Right, so I don't think terminal velocity plays a role for us Terminal velocity is only Within the small Small layer of atmosphere that we have in space. There is no terminal velocity terminal velocity would be the speed of light You know, we can't reach it Feet per second. Wow, that's a lot. So let's call it. Let's call it 50,000 Kilometers per hour and only if Only if you you want it. Okay, so let's do this Class C and S and M. So I'm assuming that's light medium and heavy weight, but let's call these the densities Class C it weighs 1.38 grams and this is going to be grams per centimeter And this is the units Actually, I should do it Here we'll just make a table we'll make the list there 1.38 2.71 so 1.38 1.38 2.71 and 5.32 5.32, right? So that's our density of asteroid made up of class C class S and class M Rocks, right? Not a formula for density. Well, this is grams per centimeter. So what we need to figure out is how many Cubic centimeters we have here of Material, right? So we want to find a volume of a sphere because this is a sphere, right? So volume of sphere, I think it's 4 3rds Pi r cubed See where you're going now Yeah, so let's check this out volume formula Let's keep that there volume formula volume Formula Come on. Just give it a volume formula. Oh volume of a sphere volume sphere. I need to say sphere Yeah, 4 3rds pi r cubed Right, so we got 4 3rds pi r cubed Okay, cool. Thanks, Josie 4 3rds pi r cubed. So volume is equal to 4 3rds pi r cubed right, so We need to figure out what the volume of this thing is in centimeters, right? So what we're gonna do is is Is convert 500 meters to centimeter, right? So let's do all these conversions down here So you see how the conversions work out too, right? And we don't have any brain farts or me making any little mistakes. Oops. You wrote down squared Did I? Oh, I wrote down squared cubed. Thank you. Yeah, cheeto brain farts not good Things don't work out. So correct me if I get it wrong anywhere. Okay, so we got 500 meters And we want to get centimeters out, right? So we're gonna multiply this by meters in the bottom 1 meter is 100 centimeters Okay, let me Write this out. So it's not messy and this is exactly what I do when I'm doing my own calculation I have to write things out, right? So 1 meter is 100 centimeters So if you multiply this out, right? The meters kills the meters you have two more zeros one two 50,000 centimeters, okay centimeters So we can find out the volume of this thing in centimeters. So four over three Pi 50,000 Cubed, okay Now what we're gonna do is write this in scientific notation Okay, I'm gonna work it out and then we're gonna erase everything put it here So we see what it is, right? We're just write it out here So we've got four thirds Pi Five times ten to the one two three four Cubed okay, so this becomes four over three pi five cubed Times ten to the power of twelve because we've got exponent to an exponent you multiply them, right? Five cubed is 125, right? So four over three pi 125 times 12 but ten to the power of 12 Does three divide into 12? Doesn't evenly but we can do it with a calculator, right? So because Three goes into 12 four times and we've got a five left over so let's do this part four over three times 125 times pi in a calculator and get a number and we're just gonna leave it as this right leave it in Scientific notation and this is where scientific notation comes in handy, right when you have gigantic numbers We're just gonna deal with it this way. So four divided by three is That times where's my pie here? Where's my pie? times 125 125 We get 500 and 23 and we're not rounding anymore. This is good enough We're not gonna go any decimal places times ten to the 12th and if we're gonna write it in scientific notation We're gonna kick this number this way To decimal places because scientific notation has to be a number a decimal and then the rest of the numbers So we went from here to here. We made the numbers smaller So we have to make this one bigger. So this becomes 10 to the power of 14 That is the volume of this asteroid. Okay So Let's Put the volume of the asteroid here 5.23 times 10 to the 14 I'm gonna erase the rest of this stuff. Okay, and I'm gonna put the Radius of this guy here Radius is equal to 5 times 10 to the 4 centimeters Okay, so let's erase this. We don't need this anymore and we're gonna erase all this And It's 5.23 times 10 to the 14 so let's put this metric here volume is 5.23 times 10 to the 14 centimeters cubed Okay 2.7 meters my math must be wrong 2.7 meters Should I check something? Should I check something? Is it 2.7? million oh million 2.7 it's I might have punched the stuff in wrong, but if we do this times 10 to the 14 it's way bigger than that, right? Because we have to do it in centimeters cubed, right? What I did was right. Okay. Good. Thank you for the confirmation Josie so we've got the volume here and the density This should be cute centimeters cubed. I believe density should be cubed right? Is it cubed? We're centimeters Given density I rolled over it It has to be it has to be cubed. Okay, cool. Thank you So it's grams per centimeter. No, it can't be grass per centimeter. It's mass for volume volume must be cubed So we just want to figure out the weight of this is Hold on a second Yeah, it is cute. It has to be cute That's right. So all you got to do now is multiply this with these numbers, right? Agreed Josie It is cute. Yeah, it is cute that has to be cute Otherwise it wouldn't make sense. So this is got to be cute Yeah, I drop exponents and accidentally write wrong numbers. This used to cost me a lot of marks on tests Okay, by the way, don't be as quick and messy as as I am. Okay, so this thing So if we want to figure out the weight of this thing, it's just going to be the volume times this, right? We'll figure out how many grams it is like a room multiplied by weight. Yeah So we're just gonna go. I'm pretty sure this is the correct way to do it, right? Because we're gonna go centimeters cubed Here, let me erase this. This is oh, yeah, this is the Velocity so velocity is five times 10 to the 4 kilometers per hour, right, I think that's what it was $50,000 $50,000 This is so awesome. Thanks for making my DJI my pleasure spider-man. Thanks for the help guys, by the way. I like this And because I don't do this With my students right now to a certain degree, right? So I like different problems that I work with Sometimes my students go an archie show you did it all or you did it all wrong, right? So what we want to do we want to go centimeters cubed times Grams per centimeter cubed, right? If you're just talking about the units and the units kill each other, so you're left with grams Right, the units sort of tell you what to do and I'm pretty sure that's all we have to do to go from density To the weight of an object, right? If I'm wrong, Josie, please let me know This isn't gonna be brutal. This is not the way you do it, right? So it's gonna be 5.2 3 times 10 to the 14 And we're gonna multiply this by 1.38 and we're gonna multiply this by 2.71 and we're gonna multiply this by 5.32 Okay, I'm writing in here because as soon as we figure out what these numbers are 5.2 3 times 10 to the 14 and 5.2 3 times 10 to the 14 Right as soon as we figure out what these numbers are we're gonna erase this and put this in another section here 7.2 2 is that this one? Yeah, that looks like it should be around 7 right? Can you punch it in? Yeah, that'd be great if you guys can provide that the numbers I'm just gonna confirm that we're talking about the same thing point two three times 1.38 Yeah, so that's it awesome nice nice nice. Thank you. So this is 7.22 7.22 times 10 to the 14 Grams right because we've got grams left over and then we got Does the US need a labor? I Don't think so sleepy waves. I don't know But one thing the United States definitely needs more of is more people littered in the language of mathematics every country needs it All right 2.78 times 10 to the 15 grams Okay So those are the Weight of this thing this asteroid coming down Right, so let's transfer these numbers here. I'm gonna erase these guys now So I'm gonna fit this and I should have written this in a table We'll do it this way We'll go wait mass wait mass mass Wait wait, I was doing way mass is the mass. No, it's the weight Masses times the gravity right so for C it's going to be 5.23 times 10 to the 14 oh G stories. I'm writing the wrong number It's going to be 7.22 times 10 to the 14 grams for S It's going to be 1.42 times 10 to the 15 grams And 4m It's going to be 7 8 times 10 to the 15 gram Right, I have a number for weight of Asteroid, but I'm waiting for your calc Okay, so this is the mass of this thing or the Way this is the mass of this thing. Oh my god. I always get it back mass equals Force mass times gravity. It's mass. It's a mass. It's mass Geez Louise mass Me and words I don't mess mess mess with It's not just names. I have a hard time with right. It's everything word related In newness the problem most people call it call it all weight so it confuses people. Yeah So let's erase these So that's mass right Now momentum is Mass times velocity Right, so momentum is Equal to mass times velocity Okay, and mass has to be in kilograms. It doesn't it's not in grams, right? So we're dealing with SI units I'm pretty sure it's got to be in kilograms. Right. I'm glad I return. This is so relaxing awesome Martin Momentum Momentum momentum. Let's check it out SI units is kilograms. It's gotta be Kilograms. Yeah, it's kilograms Mass should be in kilograms and velocity should be oh, this is this is the one I got a switch meters per second Not kilometers per hours meters per second. Thank you Josie you rock. So we got to convert kilometers per hour to Meters per second, right? So we've got a first of all change kilometers to meters. That's easy one kilometer Kilometer is a thousand meters. So kilometers kills kilometers And now we've got to do is convert hours to seconds right Thank you VIP Right chicho so glad I found a twist channel been watching you on YouTube figured I could enjoy the live experience awesome awesome Dart hooky 3600 no, I can't be three thousand six hundred. Let's do I knew my half Engineering degree before switch the software would come in and leave one thing nice So we're gonna convert hours. So we're gonna kill hours up top and we're not gonna go from hours to seconds, right? We're gonna go to minutes, right? So there's 60 minutes, right? So ours kills ours So we got meters up top. We've got minutes in the bottom. So now we've got to kill minutes. So one minute minutes is 60 Seconds right so minutes kills minutes now. We've got meters over seconds So what we're gonna do is multiply five times ten to the four by oh One hour equals three thousand six hundred seconds. Thank you. I wasn't sure where the three thousand seconds was coming Three thousand six hundred seconds coming from I'm going to inform all my patrons on the results Oh So this becomes five times ten to the four times 1,000 divided by 60 and 60 so zero takes out zero zero takes out zero Okay Now we got five divided by 36 so five divided by 36 right five divided by 36 is point 138888 so this is going to be 0.139 times ten to the hold on there's another ten here Right, so it's going to be ten to the five But then we want to write this in scientific notation is 1.39 Times ten to the we went from here to here the number got bigger so that gets smaller for okay, I Hope that in Do any brain farts here So velocity is going to be 1.39 times ten to the four meters per second Okay Hopefully I did that correctly I'm just going to leave it up if you guys want to check now. We're going to erase it. Okay So momentum is mass times velocity this times this oh this got to be in kilograms So let's erase this convert to kilograms right away Right, how many grams in a kilogram thousand grams in a kilogram looks right to me Okay, cool. I concur so thousand grams in a kilogram, right? So we're going to kick this 10 to the power of 15 down three notches So it's going to be 10 to the power of 12 kilograms. Okay, so that's grams So it's going to be 2.78 times 10 to the power of 12 kilograms This is the number we need and that's the number we need right so momentum is equal to mass times velocity mass is that 2.78 times 10 to the 12 times 1.39 times 10 to the four so 12 10 to the 12 times 10 to the four is 10 to the 610 to the 610 to the 16 so 10 to the 16 Then to the 16 and 2.78 times 1.39 2 points. What do we got 2.78 2? 7 8 times 1.39 1.39 We got 3.86 3.86 and the units of this are kilogram meters per second kilogram meters per second That's the momentum of this asteroid right Yeah awesome So that's the momentum of this asteroid Pretty serious, but What else should we figure out we should figure out the force of it force of impact is mass times Well, we don't know what it's accelerating The newtons how much force does it contain how much energy? No, we can figure out the energy. I guess can we convert to energy? Yeah, we should figure out the energy the thanks them So what's the energy formula energy energy we need an energy formula as you can tell I'm not a fan of memorizing formulas, right? I look everything up energy energy It's not volume formula formula energy One half MV squared kinetic energy. Oh, it's the kinetic energy. What yeah, that's all we've got to figure out It's just a kinetic energy. That's right We're gonna figure out the kinetic energy So kinetic energy Energy kinetic here. You know what the let's erase this and put the momentum here All right, so the momentum is 3.86 times 10 to the 16 kilogram meters per second Let's figure out how much energy that is to convert Then convert energy of the asteroid to something understandable like how many liters of water that energy could boil. Yeah, we could Let's do this. I read. I don't know how many years It's how much energy takes to boil water, but we can figure it out So that's the momentum Now we're gonna figure out the kinetic energy Kinetic energy was one half MV squared, which is going to be one half the mass is 2.78 times 10 to the 12 times the velocity 1.39 times 10 to the 4 squared. Is that what we get? You've dropped the three types of asteroids. Oh Yeah, which one? We just figured it out for this one. We'll do this one too. We'll do this one too I totally forgot the three different types of asteroid. So right now we're figuring our lower limit for how Powerful this is going to be You're just using the heaviest subject. Am I using the heaviest? I thought it was this one Did we use did we multiply by this or did we multiply by this? I totally forgot oops So this guy is going to be times 1.39 times 10 to the 4 all squared So the units of this the power of this would be 10 to the 12 times 10 to the 8 which is 10 to the 20 which is Vip has figured it out Could that asteroid boil away five Olympic size? Oh, I could probably boil away The what do you call it the Great Lakes? Right, maybe one of them make eerie. Maybe Look at your mass section. You're using heaviest. Oh, yeah, that's right. I'm using the heaviest So here we're doing a calculation for this guy right now So what was this? Oh Yeah, so this these two guys we're using these two guys The only difference between these guys is this is kilograms and that's grams right so let's do this So this is grams and that's kilograms. Thank you. I lose track of where I'm going with this stuff Sorry, I forgot to multiply by point five small wasn't it? Sorry. Yes. Okay, cool. So Okay, awesome So two points. So oh, you forgot to multiply by this. Okay, so this thing The energy of the heaviest one. So what we should do is erase this line And it's just the heaviest one we're figuring out, right? So we'll erase this as well So the kinetic energy if you punch this in it's going to be and is the comma are you? VIP Are you from Europe is the comma a decimal or is that? It's got to be a decimal because you got four digits after so it's got to be a decimal So if you multiply that out, we should get kinetic energy oops Kinetic energy is equal to 2.6 8 2.6 8 because in Europe they use Decimals yeah commas as decimals times 10 to the 20 Um Jules Newton's jupe hold on decimal comma for Newtons forces newtons energy City units Here we go Jules Jules and Jules is Jules and force are really related together less Jules and force forces. I should go what it is anyway Jules Okay So that's how many Jules of energy the heaviest one is going to have right Which is a hell of a lot? hell of a lot so For for later it takes Jules of energy to boil one liter of water from zero degrees liquid 20 degrees Jules is the units for four. Okay, awesome Jules nice You're catching me at a time where like I'm like where are we going without this, right? What's my units? I thought we're doing mathematics. So this is how much energy is going to have it takes 400,000 Jules of energy to boil water from zero to 100 degrees Celsius right boiling temperature. I Thought units for forces Newton forces Newton. Yeah, I was flipping around right, but Jules is force times Force times time force times time. No, not force times time That could be force times time as well, I guess I don't understand formulas To what but I can do the math nice. It should be pure water. I guess so let's do 400,000 420,000 so it takes 420,000 Jules of energy to take water from zero degrees to 100 degrees, right? So if we want to figure out Oops my bad Jules is a unit for energy new is the unit for force. Yeah Jules of energy to boil one liter of all our water. So right now what we've got to do is Figure out how many liters of water this thing could boil, right? So this thing would be Per liter I guess per liter Right So we want to this is how many Here Jules over liters is equal to Jules over liters. We need to figure out, right? So this is our ratio, which is 4 4200 0 and we have this many Jules, right? So 2.68 times 10 to the 20. This is just proportionality, right over this is Jules This is Jules. This is one liter. We want to figure out how many liters this will take, right? You do cross multiplication. So X is going to be equal to this divided by this, right? So let's do this so I'm just going to go 2.68 divided by 42 and then knock off three zeros for this because it's going to be this the formula Here We know what this is. So I'm just going to write it out here So X is going to be 2.68 times 10 to the 20 over 4200 and zero, right? I forgot one zero Missing a zero. Thank you little Bunga gulf Every now and then I catch when I do a repeat, right? So these four zeros are going to knock this down to 16. Now we're going to go 2.68 Here, we'll put this as a decimal too. So this becomes 15 Okay, so what we're going to do is just go 2.68 divided by 4.2 2.68 Well, you've done it. Awesome divided by 4.2. Is that it? That's it. 0.63. So right now times 10 to the 15 and I'm going to erase this So let's take this guy out. So how many liters of water can we boil? We could boil 6.39 Oops, I should put it here liters liters of water Boil is going to be 6.39 6.39 times 10 to the 15 liters Okay, and the long-term swimming pool has 2.5 times 10 to the 6 liters of water so 3.5 My cousin My cousin Borf Nice Leader, did I spell it wrong? I did spell it wrong. Leader, right? So if it's that many liters and an Olympic Swimming pool has It should be 10 to the 14. It should be 10 to the 14. Oh, yeah, I forgot to move that thing over Thank you for the correction Because I automatically moved the decimal place over. Thank you So check this out. So we got this Olympic swimming pool is Was 2.5 times 10 to the 6 liters, right? So we don't really need to worry about this. We just go 6.39 divided by 2.5 and This is times 10 to the 14 times 10 to the 6 10 to the 6, right? So what's 3.9 divided by 2.5? What tier is this? This got to be around high school. It's high school for sure high school Sorry if this is off-topic, but they just released a really hard to see teaser of Robert Patterson in the new Batsoo. Did they? Nice. I hope it's good Leaders of water and so Wow, we can't be won't it won't hit all the whole earth, right? So let's check this out. This is 6.39 6.39 divided by 2.5 2.5 is 2.56 cool. So 2.56 2.56 times 10 to the 14 minus 6 is 8 That's a lot of Olympic-sized swimming pools. What did I just read? What did they do to my man? No, it's it isn't that bad is the bat suit that bad. So this is how many swimming pools Olympic Olympic Swimming pools It'll evaporate or boil I don't know the need I don't even know who Robert Patton Pattinson is So That's how many Olympic swimming pools. How much water is in Lake Erie? Like that's a lot Oops, that's here. Let's write this out. We're gonna write this out here. Let me raise this So times 10 to the 8, right? 1, 2, 3, 4, 5, 6, 7, 8 3, 3 You could boil What does that become times 10 1, 2, 3, oh one more because there's one here 256 Million I can't be sure how long it's like an 8. It's so six zeros 1, 2, 3, 4, 5, 6 and then yeah 256 million Olympic-sized swimming pools What? Maybe Hopefully we didn't do any calculations wrong So how many pots of spaghetti could I make with all that boiled water? Looks all right DC movies are so out of touch DC Other than water pools will need a serious repair too. Yeah So seriously how much how many Olympic-sized swimming pools or how much How many leaders does Lake Erie have? Right Like I don't know. We could look that up How many leaders of water in Lake Erie? Let's see how many oops leaders of water in Lake Erie How many gallo gallons? Oh, we could figure out gallons are there Lake Erie answer You want to do the cubic centimeters? Oh, man. Where's the leader calculations? Lifetime all these numbers who's doing these mathematics present the stuff in reasonable numbers We need one more comparison to make a smaller number so we can wrap our head around it Yeah, we do Way to rock was a millions 480 Kilometers cubed Yeah, I forget where we were Well, you know centimeters Says wiki better converted convert and kilometers cube first okay, cool for 483 times 10 to the 12 Okay, cool. So we're not taking out all of Lake Erie right Cheecho which folder is best to post the bat suit in the scope of the comic books folder for sure the comic books folder, right? so Lake Erie has 4.3 times 10 to the 14 No, hold on. We've got two different answers These water in Lake Erie and Astro will boil Yeah. Oh, yeah, this was Olympic sized balls. That's how many waters So ill ill evaporate 100 Lake Erie's Wow right So fear race these So this is how much water ill evaporate Lake Erie. It will boil 75 Lake Erie's cool so Lake Erie is This is how much water will boil Right and Lake Erie you divide this by Lake Erie Lake Erie is 4.8 3 times 10 to the 12 this factor here is 100 right so With when you do this this division you end up getting you end up boiling 76 Lake Erie's That's a world event Huge huge huge an asteroid 500 meters long 500 meters and Radius right a kilometer long Will evaporate 75 Lake Erie's so the Great Lakes will be gone Right meters cute Seems like a fair bet but that energy whereas a Times 10 to the 20 joules is pretty huge. I don't know you think you did your calculation, right? 75 Lake Erie's okay pretty sure stuff. Yeah Do we discuss the material of the asteroid if it's made of iron is denser this yeah, this is what we did this is actually if it's The densest asteroid 5.3 2 right that's the Where is it? Oh my god, we did it here somewhere. Oh, yeah, we did we did it from here So we converted this to this so we went from This was the heavy asteroids, okay That's the density of heavy asteroids and we did the conversion to how much this would weigh It was a heavy asteroid and all of this calculations is the upper limit Okay, we didn't do it for this one if we do it for this one It's gonna be an order of magnitude difference Which which is a huge deal if this is an order of magnitude less at least an order of magnitude less Then we're going from 75 Lake Erie's to 7.0 7.5 Lake Erie's right Came in halfway Apparently atomic bomb fat man had that many jewels 10 to the 13 So ours is 10 to the 20 this asteroid one kilometer long will have 10 to the where is it 10 to the 13 so 10 to the power of seven right so Million plus times more energy than the atomic then fat man Right, so just imagine a million fat man is going off That's the same energy is one kilometer and that's assuming if the velocity of this thing is correct It's going at which seems really high to me Which seems incredibly high to me more is zero. I guess Calculations need one more zero apparently thought I Did the math right, but I got 70 127 trillion gallons of water then converted to liters when the lightest will still boil almost 20 Lake Erie's cool So 20 Lake Erie's 75 Lake Erie's huge Huge These what if scenarios make math exciting wish I had this in middle and high school. Yeah, really super fun doing the stuff It's just mental exercise, right? math and real life There's a reason why why I If you type in math and real life calm You'll go to my a math site that I haven't updated for a while because I need to mirror stuff any more resources to do right But math and real life is the name I chose for The website right the language of mathematics and math and real life. This is math and real life. Right. It's super cool I was born in Dunkirk, New York, which is a town that is on Lake Erie And my house was only five-minute water. That's cool. Must be cold in the winters I can just walk into a Walmart to experience experience one part That velocity seems low to me it does it based on what as Astrologer speed can be 50,000 kilometers per hour if it's low then My god, we couple orders of magnitude off, but I had to take The initial velocity is quite reasonable for what I have read in the past really That's fast 50,000 kilometers per hour asteroid One kilometer wide hitting the earth well High density will well low density to high density or evaporate anywhere between 20 to 75 Lake Erie's Wow
