A cue ball has a mass of 0.160 kg is at rest on a frictionless pool table. The ball is hit dead center by a pool stick which applies an impulse of +1.40 Ns to the ball. He ball then slides along the table and makes an elastic head on collision with a second ball with equal mass that is initially at rest. Find the velocity of the second ball just after it is struck.
