A 125 kg car moving at 12 m/s hits a 200 kg car moving at -13m/s. If the first car bounces back at -12.5 m/s what is the velocity of the second car after the collision?
1.2 m/s
2.3 m/s
3.2 m/s
4.1 m/s
Which of the following statements is not correct concerning momentum?
Momentum is a vector quantity.
An object moving at a constant speed has momentum.
If an object's velocity changes, then its momentum will also change.
Momentum is never conserved.
According to the Law of Conservation of Momentum, when two objects collide:
both objects lose momentum.
both objects gain momentum
momentum is neither lost nor gained.
momentum is always lost or gainer.
While playing a game of pool, a cue ball with a mass of 0.16 kg strikes a yellow ball which has the same mass. The velocity of the cue ball before the collision is 6 m/s. After the collision, the cue ball rebounds in the opposite direction with a velocity of -3 m/s. What is the velocity of the yellow ball immediately after the collision?

-9 m/s
3 m/s
- 3 m/s
