A .050 kg bullet is fired from a gun with a speed of 450 m/s. If the gun has a mass of 1.5 kg, What is the recoil speed of the gun?
11.7 m/s
9.0 m/s
10.5 m/s
15 m/s
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 4m/s, what is the 8 ball's velocity?
2 m/s
8 m/s
-2 m/s
6.0 m/s
In a physics experiment, two carts of mass 3.0kg each are rolled towards each other. The orange cart has a velocity of 3 m/s and the blue cart has a velocity of -2m/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
Pick all of the scenarios below that are collisions.
A catcher catches a baseball.
A pitcher throws a baseball.
Two cars smash into each other.
Two students on roller skates push away from each other.
A bug smashes into a windshield.
A projectile of mass 2 kilograms traveling at 10 meters per second collides with another projectile of mass 4 kilograms traveling at 6 meters per second in the same direction. If the projectiles "stick" together after their collision, what is their velocity after colliding?
7 m/s
8 m/s
7.3 m/s
9 m/s
A moving bomb explodes. Which equation correctly enforces the principle of conservation of momentum to determine the speed of fragment #2?
mv = m1v1' + m2v2'
m1v1 + m2v2 = m1v1' + m2v2'
m1v1 + m2v2 = mv'
m1v1 + m2v2 = m1v1 + m2v2
A 130. kg lineman moving at -3.00 m/s tackles an 90.0 kg fullback moving at +10.0 m/s. If the fullback's velocity after they collide is +3.00 m/s, what is the lineman's velocity?
2.00 m/s
8.70m/s
1.85 m/s
6.00 m/s
