>if your legs were that powerful in the first place you could simply land on the ground and survive

I suspect this is not the case.
Your legs and spine would absorb the energy of the wall, causing massive trauma.

If you, however, pushed off the chair, you would be imbuing it with your kinetic energy. The chair would be obliterated, you would survive.

Always jump with furniture. It maybe save your life.

>>7743990
It is impossible. You'd be moving too fast, and your legs wouldn't be able to create enough downward force to slow you to a safe speed. But I'm assuming you're just trolling, so carry on.

>>7744013
Imagine if you will, Chun Li, in a similar situation.

There is nothing wrong with the physics, is the point.

>>7744013
Wrong, if you were strong enough relative to your mass, (eg a grasshopper) you would be abel to do it.

> if your legs were that powerful in the first place you could simply land on the ground and survive

learn to read

When you jump from the chair, you push it with a force F, the same force F pushes you and stops you from falling.
When you hit the ground, the same force takes role, but you have to consider the biomechanics - position of legs mainly. They will have to be at velocity of 0 relative to the ground to reach the same effect as jumping from the chair..
just my two cents

The real problem is that if you pushed the chair with that much force, it would be such an enormous acceleration that your body would be destroyed just as falling to the ground would destroy it.

Merely having powerful legs is not enough, as OP said, you also need to survive kicking the chair that hard, i.e the rest of your body must also be able to withstand the forces.

(I'm oversimplifying here because the forces aren't exactly equal)

>>7744297
You're missing the point. The point is people misunderstanding this comic, ie thinking it's impossible for the wrong reasons. These are the people who think you can't move in space by throwing a rock.

To be fair, you could transfer half your momentum to the chair. Then your legs only need to be half as powerful as they'd need to be without the chair. And that only works if the chair is massive enough, because otherwise it moves away from you too fast, and there isn't enough time for you to transfer the needed momentum to it with the limited force of your legs.

>>7743990
this would work actually .
lets say there is a height you can drop from with a statistically <20% chance of serious lasting injury , with this method this height will be like 15c +- 40 higher or something like that .

practically speaking i'd much rather focus on dropping with proper form that redirects the impulse of the impact from fucking you up then use all this fancy shit .

also this is this is basically a suicide burn using a chair as propellant

>>7744318
To elaborate on this, it's only 1/2 for the limiting case of an infinite mass chair.

The constant here is the energy released by your legs, not the momentum transfer, because your legs are applying a limited force over a limited distance, not a limited time.

The momentum transfer you get is
[math]\frac{\Delta p^2}{2m_{you}} + \frac{\Delta p^2}{2m_{other}} = E_{legs}[/math]

So for the infinite mass case,
[math]\Delta p = \sqrt{2m_{you} E_{legs}}[/math]

But for finite mass,
[math]\Delta p = \sqrt{2m_{you} \frac{m_{other}}{m_{you} + m_{other}} E_{legs}}[/math]

Although at some point, the chair gets so light that you're running up against the limited velocity of your legs, not the limited force. Then the chair becomes even less effective.

>>7743990
What if your legs are powerful enough to halve the impact when the full impact would just barely kill you?

>>7744198
The funny part us, assuming you could keep the cannon pointing up, you could get enough dv to go from dying to only breaking some bones. I don't know much about clown cannons, but it could work.

Not really troll science, this is basic high school physics.

>>7744452
You mean basic biology retard? Otherwise you failed basic newtonian physics.

Physics textbooks give nonrealistic questions all the time like "how much force would you need to exert on a chair of mass m in order to have net velocity 0 given you are mass n, assume no air friction", so in context of that there's nothing wrong with it.

If you were studying basic bio on a chapter of the square cube law about how much force a creature this size could reasonably exert, then yeah this would be "troll biology".

>>7744454
only americans will get this.

If you jumped off at the same speed you were falling, you could survive. I've heard the same situation applied to a falling elevator. That being said, we don't jump very fast.

If you could shove the chair at the speed you're falling at you should be fine.

>>7746100
"shoving" a chair at a "speed"

fucking normies

>>7743990
even if this would work and your legs were strong enough, you'd still need super-human-fast eye-cognition-cerebellum coordination, which is almost impossible to obtain.

This is simple high school physics.

>>7746100
wrong. you need to shove the chair at a speed proportional to ((your mass)/(chair mass))*fall speed. But since your mass is infinite, this is impossible
