1) A pitcher in a professional baseball game throws a fastball, giving the baseball a momentum of 5.83 kg.m/s. Given that the baseball has a mass of 0.145 kg, what is its speed?

2) The lightest pilot-driven airplane ever built was the Baby Bird. Suppose the Baby Bird moves along the ground without a pilot at a speed of 88.0 km/h, Under these circumstances the momentum of the empty plane would be only 2790 kg.m/s. What is the mass of the plane?

3) In 1996, Michael Johnson ran 200.0 m in 19.32 s. Johnson’s mass at the time of his record-breaking run was about 77 kg. What was his momentum at his average speed?

4) Although it cannot sustain its top speed for more than 8.65 s, the cheetah can run a distance of 274 m during that time. If a cheetah with a mass of 50.0 kg is moving at top speed, what is its momentum?

5) The S.S. Norway is a passenger ship with a mass of 6.9 x 10^7 kg and a top cruising speed of 33 km/h. What is the momentum of the S.S. Norway once it has reached its top cruising speed?

Momentum Math Problems

In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
