I'm a jump 36 feet and break all my legs when I land
User avatar #39 to #11 - jessieqwertyu (02/10/2013) [-]
all your legs?

If you were able to jump 36 feet, your feet would be strong enough to withstand the impact going down.

You are wrong
User avatar #114 to #62 - tonkkax (02/10/2013) [-]
If you keep jumping up and down until you can jump 36 feet, the bones in your body will reinforce each jump. If you kick an iron pole, next time you kick it, it won't hurt as much. This is because whenever your muscles/bones get minor wounds in them they rebuild into stronger and stronger version of their older selves.

>humans can jump 36 ft in the air
Your bones may get tougher, but your organs don't. Also, you would require more muscle to jump that high, which is more mass. It's not even possible for a human to jump 36 feet in the air without help of a machine.

Not just your feet. Your entire body would have to be able to take the impact too. Say it was just your legs. The rest of you, following inertia and physics, would not have the strength to stop its momentum. Your pelvis would be snapped in half, organs spilling out of your gooch because the force turned them into projectiles and they punched through, your ribs would act like an accordion, spine would telescope, and your head would be somewhere in your chest cavity

get back in your locker NERD!!

Well, if the body can withstand the ability to jump into air, it should be able to land down too. The same effect when you jump happens when you fall down - your legs are pressed against the rest of your body. You would know not to throw a jump like that before you even lifted up in the air.

Depending on the direction of pull/push for your muscles, you could jump insanely high, but landing would be a different matter

Not necessarily, the force applied for the jump will be distributed over a longer period of time than the landing. Think of it like throwing an egg up into the air. While the egg will have the same energy when it leaves your hand as when it hits the ground, you know it will shatter on the ground and not while it's in your hand.

Not if you apply the same force just in the opposite order. Then it will be exactly the same motion and pressure at the same body pose.

You can't do that though, that's the problem. When you come down, you come to a stop much faster than it takes you to jump. Also, there are issues with muscle tension and it's ability to distribute forces while in different states (when jumping vs when landing). So not just would it shatter your bones, but it'd tear your tendons and ligaments as well.

you're forgetting that the time it takes you to jump would have to be really ******* short if you want to have the velocity to make it up to 36 feet. In both jumping and landing, you have to accelerate the same amount, in the same distance (leg bending etc.). So the forces could theoretically be identical

but your back wouldn't

If you were to be capable to jump 36 feet up from idle, you would be capable to land, since you need to witsand the force you would develop to jump in the frist place... All of your body would be designed to do so.
#32 to #21 - kingpongthedon (02/10/2013) [-]
But you have to keep in mind that the jump occurs over a much longer time than the stop. The power developed while landing may be orders of magnitude greater than that developed by jumping. Though the work done in each state is the same, the force needed to stop is significantly higher. It's the maximum force applied that breaks bones, not the work done at either state.

I don't quite get your point... but I think you are suggesting that you would have to train in order to land properly (like the parkour guys do) so when you land you gradually dissipate the force of the landing hit... probably you're right.

Yeah, I'd think that if one was to withstand the force of a 36 foot vertical jump, they'd sure as hell be able to land it. I'm not certain, but I'm fairly sure that the force going up would be more than the force coming down. I guess that depends on weight, perhaps...

Also relevant since cats can fall 36 feet without injury.
