What is the momentum of a baseball with a mass of 0.12 kg being thrown with a velocity of 45 m/s towards the hitter?

5.4kgm/s towards the hitter.

Explanation:

Given parameters:

Mass  = 0.12kg

Velocity  = 45m/s

Unknown:

Momentum of the baseball  = ?

Solution:

To solve this problem, we  must understand that the momentum of a body is the quantity of motion it possesses.

 Momentum  = mass x velocity

 Now insert the parameters and solve;

 Momentum  = 0.12 x 45  = 5.4kgm/s towards the hitter.
