SUMMARY
A cue ball with a mass of 0.165 kg is initially at rest on a frictionless table and is struck by a pool stick applying an impulse of +1.50 Ns. According to the impulse-momentum theorem, the velocity of the cue ball after being struck is calculated using the formula Ft = mv, resulting in a velocity of approximately 9.09 m/s. This cue ball then undergoes an elastic collision with a second ball of equal mass, which is also at rest. The final velocity of the second ball after the collision is determined to be 9.09 m/s, demonstrating the conservation of momentum in elastic collisions.
