Can u graph it , solve it , then explain why ur answer is reasonable please? The rules of tennis specify that the 0.057-kg bal must bounce to a height of between 53 and 58 inches when dropped from a height of 100 inches onto a concrete slab Part A What is the change in the momentum of the ball during the collision with the concrete assuming it bounce to a height of 56 inches? You will have to use some free-fall kinematics to help answer this question Express your answer to two significant figures and include the appropriate units Ap= 1 Value Units pValue Units Submit My Answers Give U Continue

Explanation / Answer

(56 x 0.0254) = 1.4224 metres.
(100 x 0.0254) = 2.54 metres.
V at ground when dropped = sqrt.(2gh) =sqrt(2*9.8*2.54m) = 7.056m/sec.
Momentum = (mv) = 0.057 x 7.056 = 0.402192kg/m/sec.
V from ground when bounced = sqrt.(2gh) = sqrt.(19.6 x 1.4224) = 5.28m/sec.
Momentum = (0.057 x 5.28) = 0.3kg/m/sec.
Change in momentum = (0.402192 - 0.3) = 0.102kg/m/sec
