 Cheryl, this all sounds like a great math problem. What force was applied to a backside hitting the ground? It would be your weight and then, boom, how high you jumped up, from what elevation were you starting all that? Do your kinetic potential energy. It would be this. It would be, let's do a quick little kinetic potential energy. This is the road. This is the ground. Cheryl is walking. I'm sorry. I'm putting you in a skirt. Cheryl is walking this way. I twisted too fast and I didn't want to erase it. Cheryl is walking this way. She goes, whoop, legs kick up and now she's like this. This is, that's her height. Now, potential energy you would have to start off with. Potential energy would be, potential is MGH, I'm pretty sure it's MGH. Rob Luxer, hello, hello. So mass times gravity times the height. So I have no idea how much Cheryl is going to tell us how much she weighs. I don't mind the skirt, but I, in snow, probably just a long, long parka, yeah, for sure. Long parka? Fantastic. Little fluffy goose feathers in here. So they'll pad, pad your bum, right? Okay, that's a lot of forward motion, that's a lot of forward. She was running. She was running. So whatever Cheryl's mass is, let's assume general mass, and you're going to do this in kilograms, the units here, let's write down the units for this. The units for this would be kilograms, we're going to go with SI units. Gravity would be meters per second square, and height would be in meters, okay? So let's assume they jump up one meter, one and a half meter, one and a half meter. So the mass, if we're going to do kilograms, let's take average mass for mail anyway, because I know why mass and kilograms basically, right? So my mass would be 75 kilograms, 75, 80 kilograms, 75, 80 kilograms, right? Let's go 80 kilograms, right? Times gravity, which is 9.8 meters per second square, and the height would be one and a half meters, 1.5 meters. So let's assume that's a 10, we can approximate this. 1.5 times 8 is 120, 120 times 10 is 1,200. 1,200 energy would be joules, energy is joules, not even on this physics for a while, right? 65, 65 kilograms? No, 65 is, what would that be in pounds? 65 kilograms would be 201 pounds. 65 kilograms would be around 160 pounds, I think, right? Yeah. So 1,200 joules, momentum, momentum would be, momentum we can't figure out, we need to figure out the speed first, 143 pounds, wow, wow, wow. You're at 97 kilograms, cool, cool. So 65, what do you call it, kilograms is 143 pounds, shoot, nightbot, nightbot, nightbot says, nightbot says, Rob Luxer, Rob Luxer, nightbot says, Frisage, Frisage, Frisage. Julian Assange is a publisher and journalist that has been crucified for trying to bring transparency and accountability of capitalist power to humanity. For more information, see wikileaks.org, defend.wikileaks.org, or Julian Assange and WikiLeaks playlist on censored too. Now check this out, right now that would be the beginning stages of our system in play, right? So Cheryl would have this much energy in her, right? There would be zero velocity, right? So her kinetic energy, energy, kinetic, energy, kinetic would be zero, okay? Now in physics, what we know, it's okay, oh, they're gone, nice job, in physics, what we know is we have to have conservation of energy, right? So let me erase this. I'll take this a little bit further than this, the potential energy that Cheryl has, right? I'll take it as far as I remember the formulas, right? So at the initial system, initial condition, initial, there's the total energy in the system is going to be energy potential plus energy, energy kinetic, e kinetic, e kinetic. So energy potential for Cheryl would be 1,200 joules, I think joules, man, plus zero, right? We'll kill the Eunice just in case. So 1,200 plus zero because she has zero kinetic energy. At the bottom here when Cheryl hits the ground, whap, right? She's going to have zero potential energy, but she's going to hit the ground at a certain speed, right? Just on chat, z, zypho, diddy, love science, always been a passion, always been a passion in this physics. Yeah, physics is amazing, right? The root of it being mathematics, of course, right? So initial condition is this, final condition, kinetic potential energy is zero because she's not at any height, right? Potential energy is mgh, but if her height is zero, this is our zero, the ground, right? Well anything, whatever the mass is, times whatever gravity is, which is 9.8 times zero, it's just zero. So her potential energy is going to be whatever the potential energy, which is zero, and she's going to have a kinetic energy, and kinetic energy, k kinetic, energy kinetic is one-half mv squared, right? Yeah, one-half mv squared, help message. If the radius, this is from our last, yesterday, what is the volume of the bearing of the energy? We definitely have to allow that, links up to our previous thing, right? So one-half mv squared. So we have to figure out what her velocity is going to be, right? And this, right? This has to be zero plus one-half mv squared, right? We don't know what her velocity is going to be, right? We know what her mass is, or what my mass is, 80 kilograms, right? So what's going to happen is, in physics, you've got conservation of energy. Energy initial must equal energy final. So energy initial must equal energy final. Energy initial is 1,200, energy final is one-half mv squared. Now the m, usually, not usually, but sometimes when you do this, you don't plug in the numbers right away. You leave it as a formula because the mass is going to kill the mass, right? On this side. This side is mgh, right? The m is going to kill the m. But let's put it in, right? So this is going to be 1,200 is equal to one-half 80v squared. It goes 40 times divided by 40 divided by 40, zero kills zero, 120 divided by four is 30 v squared. Bring this here. So velocity is going to be squared with 30 meters per second, okay? That's how fast she's going to be hitting the ground, right? What is that in kilometers per hour? Should we do conversion to kilometers per hour so we get a feel for how fast this is? Right? Let's do converted to kilometers per hour, okay? And then we'll figure out the momentum, right? The difference is momentum is mv, right? I'm always calling an ambulance for sure. I'm already calling an ambulance for sure. So square root of 30, right? Let's, here, we'll leave it as square root of 30. So square root of 30 meters per second, okay, hitting the ground. We want to convert this to kilometers per hour just to get a visual of how fast that is. So if you're going to convert anything from meters per second to kilometers per hour, kilometers per hour, right? What you need to do is you've got to get rid of the seconds here. So you put seconds here and seconds is a quick jump to minutes, right? So seconds, we're going to convert to minutes. The conversion rate there is one minute is 60 seconds, but we want hours in the bottom. So hours, we're going to put minutes here, and there's minutes as a direct conversion to hours, so we're going to put hours here. So one hour is 60 minutes, right? So seconds kills seconds, minutes kills minutes. We've got hours in the bottom, which is what we need it, right? And then what we want, we want to convert meters to kilometers because we want kilometers in the top. So what you do is you put meters in the bottom, meters is a direct conversion to kilometers, you put kilometers here, and one kilometer is a thousand meters, right? And this conversion, if you do this multiplication, a square root of 30 times 60 times 60 divided by a thousand will convert it to kilometers per hour. So let's kill off the zeros first. One zero kills one zero, one zero kills one zero, two goes into this five times, two goes into this three times, three times six is 18. It's going to be here, we'll write it down here. Square root of 30 times 18 divided by five, right? Let's just do this with a calculator. Oh, you're missing the little bit of bottom here. Let me make this five so you see it. Let's make it bigger so you actually see the five, five, right? So let's punch this into a calculator, what do we get? 30 square roots times 18 divided by five. So that's 98.6 divided by five, which is just basically going to be 20, right? So 19.7, okay. So 19.7 kilometers per hour, which is basically 20 kilometers per hour, 20 kilometers per hour. So if you want to get a feel of how hard Cheryl is going to hit the ground, just imagine someone standing and a car driving at 20 kilometers per hour hits them, boom, right? Now 20 kilometers per hour doesn't seem that fast, but when you have a force, solid force hitting you at 20 kilometers per hour where the force doesn't move and you're the only thing that's going to be moving because their weight is infinite compared to yours and the ground's weights is infinite compared to Cheryl's weight, okay? Like coming off a fast bike. Like coming off a fast bike but you're not rolling, right? You wouldn't be rolling, you wouldn't be, what do you call it, slowing down your impact in any way, right? And you're hitting, coming off a fast bike, not hitting the ground but jumping in the air and hitting a solid wall, boom, right? Because everybody's wiped out on a bike. When you wipe out on a bike, you got wiped out. Sometimes you're going really fast but when you wipe out, the ground is on the ground and you can roll and you're not going into a wall, right? Cheryl, I had a bruise that matched the math. I'm not thinking it's time to swap. Yak tracks for full Grand Pond. I have no idea what those are but okay. Pond, we have a formula for how long it takes to clear snow from the highway in the UK. It's roughly Canada's time taken for the same task multiplied by 50 plus traffic delays from school mums crashing their cars, hilarious. And that's because the UK doesn't get as much snow as Canada, right? Not even close. Oh my God, I have come off a fast bike. It's like hitting a wall if you're tossed, yeah, if you're tossed, yeah. But man, hard. As far as the momentum of this, as far as the momentum, momentum is, um, mv, I think, man, I hope I'm right, um, mv, mv, I think so, man, I haven't done this for a while. I'm going to look this up. If someone wants to confirm, please do. Momentum formula, momentum formula, and change in velocity, yeah. So momentum is velocity, mass times change in velocity, right? Joe Chicho, is there a way to convert that into G-Force? Um, yeah, I don't know how to do it. I don't know the formula. G-Force, there was a crash in the recent Formula One season where a driver crashed and experienced 51 G-Force, 51 times the force of gravity? No, it couldn't have been 51. That would crush, that would make him, like a pancake, 51 G-Force, you sure about Joe? Like when fighter jets fly and stuff, I think human beings pass out at 5G or something. Many human beings pass out when they experience, uh, five times the force of gravity, right? He hit the barrier sideways at about 160 miles per hour, 6G, 51 G, no, 51 G-Force is not 6G, is it? Or Ronnie, are you saying people pass out at 6G? I think pass out for fighter jets is 6G. If you know, Joe, if you're comfortable with that, um, with those numbers, we can do a direct ratio comparison. That's all we need to do. So we don't need the formula. We can just do a ratio comparison because we're going to have, um, what do we need? We have Cheryl's speed. So we can convert kilometers per hour to miles per hour and then just do a ratio comparison. Right? Hello on the snake, hey, G-Cho, I've been studying some math lately. I've got a question. Let's say you were riding a motorcycle that goes 200 miles per hour and you were chasing a car that was going 160 miles per hour, you're 1,000 feet, 34 meters away from the car. How many seconds will it take to be parallel to the car? Yeah, we can do this question. Hello on the snake. Bring it up. Uh, now post it again as soon as we finish this discussion and then we can do it. Uh, Ronnie, yeah, I've seen YouTube videos where pilots pass out at 6G, 6G, so cool. 1G is about 22 miles per hour a second, I think. Is it? Is it that low? No. I can't be that low. Is it that low? 1G? I think 51G was a force which people pressed the off button on their TV remote after they stole the championship from Lewis Hamilton. Funny, funny, funny. So if that, I can't be 51G, 51G with the insane first time chat. What are we drawing? We're calculating, uh, how hard someone will hit the ice if they, if they had freezing rain come down. So if they slip and if they're falling from a height of 1.5 meters, 1.5 meters, we calculated how fast they're going to hit the ground, which is going to be 20 kilometers per hour, or equivalent to, uh, the square root of 30 meters per second, okay? So now what we're going to do is figure out what their momentum is going to be, which is going to be 80 kilometer, 80 kilograms times the square root of 30. So 80 times the square root of 30. What is that? 80, 8 times 30 square root. Their momentum is going to be 438. 438. Now what's the units of momentum? Joe, it would have been later lateral G and not vertical G, okay? Which is, uh, what fighter pilots experience, okay? So the G is, is, uh, this way. Not verticals. I wouldn't, wouldn't mean. I don't know. I don't know the terminology on this stuff. What is momentum? Momentum? Units of momentum, uh, force? No, momentum would be, what's, uh, I can't believe this formula doesn't have the units. Come on. Anybody know what the units of momentum are? It was instant as well. Lasted far less than one second. Wow. I just want the word for it. It's not, it's not jewels, is it? No, it can't be jewels. I'm just reading a website right now where, oh, come on, unit. SI unit for wanting, oh, there's no word for it. Kilograms, uh, meters per second. Yeah. We know that. But isn't there a word for it? Kilograms, meters per second, momentum, units. This is so difficult. SI, what is the unit of momentum also called? Kilogram, kilogram meters per second. That's all it's called. There's no word for it. Kilogram meters per second. Okay. Kilogram meters per second. That's what momentum would be, right? Because mass is kilograms, velocity is meters per second. Kilogram meters per second. Yeah. Not a good experience. Sliding on ice, flying up into the air and boom, solid impact into the ground. And if there's stairs here, if this happens to you on stairs, just imagine walking downstairs, walking downstairs, right? And you fly up into the air, come down, and just imagine, because this force is going to be distributed along your whole body if you hit a flap, which is a good thing to do, right? Except the head, protect the head. If you come down and hit one of these ledges, all that force on a little corner,
