Which of these equations is used to calculate momentum?

• p = mv

• p = m/v

• p = m + v

• p = v/m

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

• m = 400

  v = 15

• m = 100

  v = 100

• m = 1000

  v = 50

• m = 1500

  v = 2

• m = 2000

  v = 2
