the maximum height a typical person can jump from a crouched start is about 60cm. By how much does the gravitational potential energy increase for a 72kg person in such a jump? Where does this energy come from?

I know the formula for gravitational potential energy is U=mgh. I just don't know what to plug in =/

72 * 9.81 * 0.60 in Joules
It comes from the kinetic energy at liftoff
