A tennis ball is released from height h above ground level. If the ball makes inelastic collision with the ground, to what height will it rise after third collision Share with your friends Share 1 Sanjay Singh answered this Dear student Let coefficient of restitution be e.Velocity with which it hits the ground is v2-u2=2ghv2=2ghv=2ghvelocity with which it rebounds after first collision is V1V1=e (Velocity with which it hits the surface)V1=e×2ghvelocity with which it hits the ground second time isv2=e×2ghvelocity with which it rebounds is V2V2=e×(e×2gh)=e2×2ghvelocity with which it hits the ground third time isv3=e2×2ghvelocity with which it rebounds is V3V3=e×(e2×2gh)=e3×2ghMaximum height reached for the third time ish3=V232g=e6×2gh2g=e6×hRegards 2 View Full Answer
