Law of Conservation of momentum

What does the law of conservation of momentum mean?

• it is what happens when a collision happens.
• it tells what momentum is.
• it is what gravity does.
• it is speed.

What happens when a collision takes place?

• The objects fling backwards.
• The objects stay in place.
• One object takes the momentum of The other and propels forward
• The object goes up.

If a 5-kg bowling ball is projected upward with a velocity of 2.0 m/s, then what is the recoil velocity of the Earth (mass = 6.0 x 1024 kg).

• v = 1.67*10-24 m/s (downward)
• v=124*13-53 m/s (downward)
• v=12*4-6 m/s (downward)
• v=65*87-3 m/s (upward)

If a ball is projected upward from the ground with ten units of momentum, what is the momentum of recoil of the Earth? Do we feel this?

• We feel it because the earth vibrates, and we can feel the vibration. 
• It isn't felt by sane people.
• The earth recoils with 10 units of momentum. It is not felt.
• We feel it all the time.

A large truck and a Volkswagen have a head-on collision. Which vehicle experiences the greatest force of impact?

• The large truck.
• They are both the exact same,
• The volkswagen
• Neither, the road does.

(continued from question 5)
Which vehicle experiences the greatest acceleration?

• Neither, a car passing them does.
• They are the same.
• Acceleration is greatest for the Volkswagon. 
• The truck has the greatest.

If a car runs into a truck, will the truck be propelled forward?

• Yes, it will.
• Both will stay the same
• they both will be flu
• No, the car will be propelled back.
