    A steel ball of mass m = 1 kg and a cord of negligible mass and length L = 2 m make up a simple pendulum that can pivot without friction about the point O (see below). This pendulum is released from rest in a horizontal position and when the ball is at its lowest point it strikes a block of mass m = 1 kg sitting at rest on a shelf. Assume that the collision is perfectly elastic and...
