MOMENTUM A golf ball is released from rest from a height of 0.811 m above the ground and has a collision with the ground?

A golf ball is released from rest from a height of 0.811 m above the ground and has a collision with the ground, for which the coefficient of restitution is 0.601. What is the maximum height reached by this ball as it bounces back up after this collision?

    Ignoring air resistance

    Velocity just before ground impact

    v₀ = √(2gh) = √(2(9.81)(0.811)) = 3.9889... m/s

    Velocity just after rebound

    3.9889(0.601) = 2.3973... m/s

    height reached after rebound

    h = v²/2g = 2.3973² / 2(9.81) = 0.2929... ≈ 0.293 m

    coefficient of restitution 0.601 applies to velocity, therefore :

    h  ≡ V^2

    h' ≡ 0.601^2*V^2

    h'/h = 0.361

    h' = 0.811*0.361 = 0.293 m
