16-42. The 5-lb ball is shot from a spring device. Thespring has a stiffness k = 10 lb/in. and the cables Cand plate P keep the spring compressed 2 in. The plateis pushed back 3 in. from its initial position, so thats = 30 in. If it is then released from rest, determine thespeed of the ball when it leaves the surface of thesmooth inclined plane.www30°Prob. 16-42
