Question:
A cue ball at rest on a frictionless pool table is hit dead center by a pool stick, giving it an impulse of +1.50 Ns. The ball slides (the combination of hitting the ball dead center and no friction allows this to happen) along the table and makes a head-on elastic collision with another pool ball. If both pool balls have a mass of 0.166 kg, determine the velocity of the second ball the instant after the collision.
