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
