Questions and Answers
  • 1. 
    The momentum of a body is equal to its mass multiplied by its velocity.
    • A. 

      True

    • B. 

      False

  • 2. 
    A ball of mass 3kg is moving to the right with velocity 3m/s and a ball of mass 1kg is moving to the left with velocity 2m/s. we can use the principle of conservation of mass to determine the velocity of the other ball after the collision.
    • A. 

      True

    • B. 

      False

  • 3. 
    What is true about impulse and momentum
    • A. 

      Impulse deals with velocity while momentum deals with change in velocity

    • B. 

      Impulse is mass times velocity while momentum is force times time

    • C. 

      Momentum is the mass of a substance multiplied by the velocity while impulse is just the change of momentum

    • D. 

      Momentum and impulse are unrelated to each other

  • 4. 
    A 71.25 kilogram motorcycle is moving at a speed of 33.75 m/s. What is the momentum of the cycle?
    • A. 

      Equal to 200 kg m/s

    • B. 

      Greater than 200 kg m/s

    • C. 

      Less than 200 kg m/s

  • 5. 
    A small car (mass = 71.25 kilograms), moving at 52.5 m/s, crashes head on with a 285 kilogram truck moving at 33.75 m/s in the opposite direction (negative velocity). If the two cars become intertwined and mangled (inelastic), with what velocity does the wreckage move? (Don't forget direction!)
    • A. 

      A magnitude lesser than 30 m/s moving in the initial direction of the car

    • B. 

      A magnitude lesser than 30m/s moving in the initial direction of the car

    • C. 

      A magnitude lesser than 30 m/s moving in the initial direction of the truck

    • D. 

      A magnitude greater than 30 m/s moving in the initial direction of the truck

  • 6. 
    Because of the principle of conservation of momentum, a rocket can get rid of its empty stages
    • A. 

      To decrease velocity

    • B. 

      To maintain velocity

    • C. 

      To increase mass

    • D. 

      To increase velocity

  • 7. 
    A 50 kg skateboarder is riding his 2.3 kg skateboard at a speed of 4 m/s.What is his momentum?
    • A. 

      Greater than 200 kg m/s

    • B. 

      In between 100 and 200 kg m/s

    • C. 

      Less than 100 kg m/s

  • 8. 
    A 0.2 kg red cue ball rolling at 1.4 m/s elastically collides directly with a 0.2 kg 9-Ball at rest.Which of the following is true?
    • A. 

      The 9-ball would have a velocity greater than 2 m/s

    • B. 

      The 9-ball would have a velocity greater than 0.5 m/s but less than 2m/s

    • C. 

      The red cue ball would have a velocity greater than 1.0 m/s

    • D. 

      The red cue ball would have a velocity of 0 m/s

    • E. 

      The two cue balls would stick together and have the same velocity

  • 9. 
    In a perfectly elastic collision, a ball dropped from a certain height would bounce
    • A. 

      At a greater height

    • B. 

      At the same height

    • C. 

      At a lesser height

    • D. 

      Would stick to the floor

  • 10. 
    In a perfectly inelastic collision, a ball dropped from a certain height would bounce
    • A. 

      At a greater height

    • B. 

      At the same height

    • C. 

      At a lesser height

    • D. 

      Would stick to the floor
