Atennis 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? 12 cm 120 cm 140 cm 120 mm

Here initial total potential energy of the ball is given by

now on each bounce it will lose 16% of the energy

so at each bounce it will have 84% of initial energy

so here we will have total energy after first collision

After 2nd collision total energy is given as

now after third collision the final energy is given by

so the final height is given as

so after third bounce its height will be 1.185 m
