In a game of pool, the white cue ball hits the #5 ball and stops, while the #5 ball moves away with the same velocity as the cue ball had originally. The type of collision is

Answer: elastic

In an elastic collision, if the momentum is conserved, then which of the following statements is true about kinetic energy?

Answer: Kinetic energy is also conserved

A 3.0-kg object moves to the right at 4.0 m/s. It collides in a perfectly inelastic collision with a 6.0 kg object moving to the left at 2.0 m/s. What is the total kinetic energy after the collision?

Answer: 0 J

Two objects collide and stick together. Kinetic energy

Answer: is definitely not conserved
