A force of 186 N acts on a 7.3 kg bowling ball for 0.40 s.

1. What is the ball's change in momentum?
2. What is its change in velocity?

Answer :

Final answer:

The change in momentum of the bowling ball is 74.4 kg·m/s, and its change in velocity is 10.2 m/s.

Explanation:

To calculate the change in momentum of an object, we can use the formula:

Change in momentum = force x time

Using the given values:

Force = 186 N
Time = 0.40 s

Substituting these values into the formula, we get:

Change in momentum = 186 N x 0.40 s = 74.4 kg·m/s

To calculate the change in velocity, we can use the formula:

Change in velocity = change in momentum / mass

Using the given mass of the bowling ball (7.3 kg) and the calculated change in momentum (74.4 kg·m/s), we can calculate the change in velocity:

Change in velocity = 74.4 kg·m/s / 7.3 kg = 10.2 m/s
