Question

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?

140 cm

120 cm

120 mm

12 cm

Anything higher than i’d say 70 cm is false and it’s way to much. Thank you!!!
