A steel ball weighting 1 kg is fastened to a cord 1 m long and is released when the cord is horizontal . At the bottom of its path the ball strikes a 5-kg steel block initially at rest on a frictionless surface . The collision is elastic . Find the speed of the ball and speed of the block just after collision . (g = 9.8ms−2) [Hint : Apply principal of conservation of momentum and conservation of kinetic energy as the collision is elastic .]
