1. In an elastic collision, which of the following quantities is conserved?
Kinetic energy only
Momentum only
Both kinetic energy and momentum
Neither kinetic energy nor momentum
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
1. In an elastic collision, objects stick together after impact.
True
False
2. The total momentum of an isolated system remains constant in the absence of external forces.
True
False
1. In an elastic collision, both and are conserved.
2. The unit of momentum is .
1. A 4 kg bowling ball moving at 8 m/s strikes a 1 kg pin at rest. If the collision is elastic, and the bowling ball continues in the same direction at 4.8 m/s, what is the velocity of the pin after the collision?
2. Explain the difference between an elastic and an inelastic collision in terms of kinetic energy.
