## Main Question or Discussion Point

Hi I like to play basketball and am curious as to how much force is required to jump a certain height I have tried to calculate it but I get stuck at energy and am not sure how to find the force as it is difficult to measure without equipment and being very accurate and precise (unless there is something obvious I could be doing and am missing).

I have done the following calculations already:

my average vertical jump is 27 inches and for calculations and 27 inches = .6858 meters and my desired vertical is 30 inches = .762 meters

so using the change in gravitational potential energy Eg=mgΔh (my mass is 67.1317kg)

Eg=(67.1317)(9.8)(.6858) and for my desired 30 inch vertical use (.762)m

Eg=451.18 J ^ which Eg=501.31 J

and with that if I wanted I could find out my take off speed by using the kinetic energy equation. But my main problem is what amount of force did I provide against the ground to get that speed.

finally once I have found the force could I use the equation Fg=mg and using the force calculated to jump that high could I find the mass if I were to squat or lift I would then be able to jump that high?

Thanks in advance for insight/comments
