Hi there,(adsbygoogle = window.adsbygoogle || []).push({});

I'm interested in the force required to jump. It's been a decade since physics, my old copy of Serway is 1,000 miles away, and I can't remember enough about solving the problem to put proper keywords into a Google search (yeah, it's pathetic).

I remember enough about Newtonian kinematics and projectile motion to solve or derive for initial velocity/time of flight/etc, but I can't remember how to relate initial velocity to force. Is there an instantaneous acceleration at the moment of lift-off while jumping? Can I use the F=MA equation, or do I need to look at kinetic energy?

Ultimately, I'd like to know how jump-height changes with body strength (if I were twice as strong, how much higher could I jump?). Would anyone be willing to walk me through the process of solving this, please?

Thanks in advance,

Plebe
