A tennis ball is released from a height of 2.0 m above the floor, and then bounces three times. With each bounce, dissipative forces cause it to lose 16.0% of its mechanical energy. How high does it reach after the third bounce?

Question

anonymous · Answer

u know the formula for potential energy

mrnood · Answer

the height is DIRECTLY proportional to potential energy
the energy reduces by 16% 3 times

so has .84*.84*.84 of original

so height is proportional to this loss in energy
