Momentum Physics Example 3

Follow the full solution, then compare it with the other examples linked below.

Example 3

easy
What velocity must a 0.5 kg0.5 \text{ kg} ball have to possess a momentum of 15 kg m/s15 \text{ kg m/s}?

Solution

  1. 1
    Use p=mvp = mv and solve for vv.
  2. 2
    v=pm=150.5=30 m/sv = \frac{p}{m} = \frac{15}{0.5} = 30 \text{ m/s}

Answer

v=30 m/sv = 30 \text{ m/s}
Rearranging the momentum formula lets us find any one of the three quantities (momentum, mass, velocity) when the other two are known.
