Question

1. two bowling balls, red and gray, are rolling with the same velocity. the red bowling ball has a mass of 5.90 kg, and the gray bowling ball has a mass of 7.20 kg. which statement about these bowling balls is accurate?

the two bowling balls have the same amount of inertia.
the gray bowling ball has more inertia than the red ball
since the balls are not accelerating, they have no inertia
the red bowling ball has more inertia than the gray ball

Explanation:

Inertia is a property of matter that depends on mass. The greater the mass of an object, the greater its inertia. Here, the gray bowling ball has a mass of \(7.20\space kg\) and the red one has a mass of \(5.90\space kg\). Since \(7.20> 5.90\), the gray ball has more mass. So, it has more inertia. Also, all objects with mass have inertia, regardless of whether they are accelerating or not.

Answer:

The gray bowling ball has more inertia than the red ball.
