Meriam, Kraige & Bolton — Kinetics of Particles: Problem 3_199

3/199 A tennis ball is projected toward a smooth surface with speed \(v\) as shown. Determine the rebound angle \(\theta'\) and the final speed \(v'\). The coefficient of restitution is 0.6. Initial conditions (from diagram): Initial speed = \(v\) Angle of incidence with the surface = \(45^\circ\) Final speed = \(v'\) Rebound angle with the surface = \(\theta'\) Coefficient of restitution \(e = 0.6\)
