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