>>507105020The maximum jump speed you can produce with your legs is around 2–3 m/s (meters per second) at best. If you're falling at 50 m/s, subtracting 2 m/s by pushing off the chair would still leave you falling at 48 m/s.
Average vertical jump speed is around 2–3 m/s upward, max for elite athletes is 4–5 m/s. This is nowhere near enough.
You’d need to reverse your 44.3 m/s downward speed — that means jumping upward at 44.3 m/s relative to the ground.
You would need superhuman legs capable of exerting over 15,000 newtons of force in a fraction of a second — something not remotely achievable by any human or animal. This is physically impossible with normal biology.
Could be done with a rocket or spring-boosted mechanism:
If your robotic system:
Stored huge amounts of energy (like a high-tension spring or compressed air tank)
Was actively controlled for balance and timing
Could fire with extreme precision and force
Then yes — in theory, you could survive such a fall using a robotic leg thruster system, but you’re now closer to a controlled rocket landing or impulse propulsion system (like Iron Man boots or spring-loaded legs from cartoons).
Yes, with robotic assistance powerful enough to reverse your fall velocity, it could theoretically work.
