A 1.0-kg steel ball and a 2.0-m cord of negligible mass makeup a simple pendulum that can pivot without friction about thepoint O, as in the picture below. This pendulum isreleased from rest in a horizontal position, and when the ball isat its lowest point it strikes a 1.0-kg block sitting at rest on ashelf. Assume that the collision is perfectly elastic andthat the coefficient of kinetic friction between the block andshelf is 0.10.

(a) What is the velocity of the lbock just after impact?

(b) How far does the block slide before coming to rest(assuming that the shelf is long enough)?
