A baseball has a mass of 0.45 kg and is thrown with a speed of 25 m/s. What is the momentum of the baseball?

0.018 kg • meters squared per second

11 kg • meters per second

56 kg • meters per second

140 kg • meters per second

The second option: 11 kg * m/s

Explanation:

Recall that linear momentum is defined as the product of the mass times its velocity, therefore in this case, the mass is 0.45 kg, and the speed is 25 m/s, therefore the linear momentum is:

P = m * v = 0.45 Kg * 25 m/s = 11.25 kg * m/s

So roundng the answer to the nearest whole number, you get 11 kg * m/s, which is the second option they give you.
