You are calculating the momentum of a 2 kg toy car moving along the sidewalk at a speed of 0.5 m/s. What would happen to the momentum if you doubled the mass of the car?

• You would double the momentum.

• You would triple the momentum.

• You would half the momentum.

• The momentum would not change.

Calculate momentum and put them in order from GREATEST to LEAST momentum. (1st one should be the largest)

• m = 1500

  v = 2

• m = 1000

  v = 50

• m = 2000

  v = 2

• m = 400

  v = 15

• m = 100

  v = 100
