A steel ball with mass 1 kg strikes an initially stationary plate of mass 2 kg with an initial velocity 24 m/s at an angle 60◦. If the plate is constrained to move vertically, and the coefficient of restitution for the impact is e = 0.8, compute the magnitude of velocity v2 and the direction θ2 with which the ball rebounds off the plate immediately after the impact.
