# 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?

Since the coefficient of restitution is equal to the ratio of the velocities, the coefficient squared is equal to the ratio of the energies. That tells us that

h₁ = h₀*e² = 0.811m * (0.601)² = 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
