A 3.6 kg steel ball and 1 m cord of negligible mass make up a simple pendulum that can pivot without friction about the point O. This pendulum is released fromrest in a horizontal position and when the ball is at its lowest point it strikes a 1.4 kg block at rest on a shelf.
Assume that the collision is perfectly elastic and take the coefficient of friction between the block and shelf to be 0.98.
How far does the block move before coming to rest? The acceleration due to gravity is 9.81 m/s2
