2. In an elastic collision, both energy and are conserved.
1. Briefly explain the difference between an elastic and an inelastic collision.
2. A billiard ball (mass = 0.17 kg) traveling at 2.0 m/s strikes another identical billiard ball at rest. After the elastic collision, the first ball comes to a complete stop. Calculate the velocity of the second ball after the collision.
