Momentum

Practice

Review how to calculate momentum, and then solve the problems at the bottom of the Web page. (listed below)

1. Calculate the momentum of a 0.15 kg ball that is moving toward home plate at a velocity of 40m/s.

2. Which has greater momentum, a 2.0 kg hockey puck moving east at 2.5 m/s or a 1.3 kg hockey puck moving south at 3.0 m/s?

3. A track athlete throws a 2 kg discus into a field with a velocity of 21 m/s. What is the momentum of the discus?

4. Calculate the momentum of a 700 g ball that is rolling down a ramp at 4.6m/s.

5. A cannon fires a 40.5 kg shell toward a target and the shell moves with a velocity of 120 m/s. Calculate the shell's momentum.

Review

  1. Define momentum.

  1. Write the equation for calculating momentum from mass and velocity.

  1. What is the SI unit for momentum?

  1. Which skateboarder has greater momentum?

  1. Skateboarder A: mass = 60 kg; velocity = 1.5 m/s
  2. Skateboarder B: mass = 50 kg; velocity = 2.0 m/s
