Linear Momentum Revision Questions

1) A 3 kg object has the same linear momentum as a 12 kg object moving at 4 m/s due north. What is the velocity of the first object?

  1. 16 m/s
  2. 9 m/s
  3. 16 m/s due north
  4. 9 m/s due north

Correct Answer: C

2) A 300 g ball moving at 8 m/s hits a hard surface and turns back at 6 m/s. What is the change in momentum the object experiences during this process?

  1. 0.6 kg × m / s
  2. 4.2 kg × m / s
  3. 15.0 kg × m / s
  4. 14.0 kg × m / s

Correct Answer: B

3) What change does occur in the amount of motion of a 20 g bullet moving initially at 400 m/s if it stops after plunging on tree trunk?

  1. It decreases by 1600 kg × m / s
  2. It increases by 1600 kg × m / s
  3. It decreases by 8 kg × m / s
  4. It increases by 8 kg × m / s

Correct Answer: C
