Read each question carefully and answer to the best of your ability. Show all work for calculation problems.
1. In an elastic collision, which of the following quantities are conserved?
Momentum only
Kinetic energy only
Both momentum and kinetic energy
Neither momentum nor kinetic energy
2. A 2 kg ball moving at 5 m/s collides elastically with a stationary 3 kg ball. What is the total momentum of the system before the collision?
0 kg·m/s
10 kg·m/s
15 kg·m/s
25 kg·m/s
3. In an elastic collision, the total of the system is conserved, as is the total .
4. The coefficient of restitution for a perfectly elastic collision is .
5. Explain the difference between an elastic and an inelastic collision. Provide an example of each.
6. A 10 kg object moving at 4 m/s to the right undergoes an elastic collision with a 5 kg object moving at 2 m/s to the left. Calculate the final velocities of both objects after the collision.
7. In all collisions, momentum is conserved.
