The maximum height a typical human can jump from a crouched start is about 55.0cm .

Question:

By how much does the gravitational potential energy increase for a 80.0kg person in such a jump? Where does this energy come from?

Answers

U = mgh, m=64kg, g= 9.8m/s^2, h= 55.0cm or 0.55m

U= (64kg)(9.8m/s^2)(0.55m)

U= 345 J
