KE decreased by 230J
PE increased by 230J = mgh
So, find h
A 33-kg girl is bouncing on a trampoline. During a certain interval after she leaves the
surface of the trampoline, her kinetic energy decreases to 195 J from 425 J. How high
does she rise during this interval? Neglect air resistance.

adding on to steve its h = 230/30*9.8 = 0.78
