Find the speed of the ball just after collision

Reference no: EM13542441

A steel ball of mass 0.400 kg is fastened to a cord that is 80.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal. At the bottom of its path, the ball strikes a 3.00 kg steel block initially at rest on a frictionless surface. The collision is elastic.

(a) Find the speed of the ball just after collision.
(b) Find the speed of the block just after collision.
