Question

A 0.15-kilogram baseball thrown at a speed of 50 meters per second and a 7.25-kilogram bowling ball rolling at 2 meters per second are both stopped in 0.2 seconds.

a. The baseball is stopped with less force because it has less inertia.
b. The baseball is stopped with less force because it has less momentum.
c. The bowling ball is stopped with less force because it has less momentum.
d. The bowling ball is stopped with less force because it has less inertia.

Answer 1

The baseball is stopped with less force because it has less momentum.

Step-by-step explanation:

The correct answer to this question is b. The baseball is stopped with less force because it has less momentum.

Momentum is the product of an object's mass and velocity. The formula for momentum is:

momentum = mass × velocity

Since the baseball has a smaller mass and a smaller velocity compared to the bowling ball, it has less momentum. When both objects are stopped in the same amount of time, the object with less momentum experiences less force. Therefore, the baseball is stopped with less force.
