A tennis ball is released from a height h\text{h} and after freely falling on a wooden floor it rebounds and reaches height h/2\text{h} / 2. The velocity versus height of the ball during its motion may be represented graphically by: (graphs are drawn schematically and on not to scale)A tennis ball is released from a height h and after freely falling on a wooden floor it rebounds and reaches height h /A tennis ball is released from a height h and after freely falling on a wooden floor it rebounds and reaches height h /A tennis ball is released from a height h and after freely falling on a wooden floor it rebounds and reaches height h /A tennis ball is released from a height h and after freely falling on a wooden floor it rebounds and reaches height h /
