While playing pool, the white cue ball strikes the 8 ball. Before the collision, the cue ball's velocity was 10 m/s and the 8 ball was at rest. If both ball's have a mass of 0.15 kg and the cue ball's velocity after the collision is 2 m/s, what is the 8 ball's velocity?

2 m/s

8 m/s

-2 m/s

1.5 m/s

Two skaters begin at rest. Skater 1 has a smaller mass than Skater 2. After they push off each other,...

Skater 2 experiences a greater change in momentum

Skater 1 has a greater velocity than Skater 2

Skater 1 experiences a greater force

In a physics experiment, two carts of mass 1.5 kg each are rolled towards each other. The orange cart has a velocity of 2 m/s and the blue cart has a velocity of -1m/s. The carts stick together when they collide. Calculate their final speed.

0.5 m/s

1.0 m/s

0.33 m/s

0.67 m/s

Two football players with mass 75 kg and 100 kg run directly toward each other with speeds of 6 m/s and -8 m/s respectively. If they grab each other as they collide, the combined speed of the two players just after the collision would be:

-2.0 m/s

3.4 m/s

-4.6 m/s

7.1 m/s

A .030 kg bullet is fired from a gun with a speed of 350 m/s. If the gun has a mass of 0.9 kg, What is the recoil speed of the gun?

11.7 m/s

9.0 m/s

10.5 m/s

10 m/s

A large box slides across a frictionless surface with a velocity of 12 m/s and a mass of 4 kg, collides with a smaller box with a mass of 2 kg that is stationary. The boxes stick together. What is the velocity of the two combined masses after collision?

0 m/s

4 m/s

8 m/s

12 m/s

What is an elastic collision?

An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies is different.
