Homework Help: physics

Posted by physics on Tuesday, December 7, 2010 at 7:36pm.

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 =/
