Chapter 12, Problem 28A

Which will have the greater acceleration rolling down an incline—a bowling ball or a volleyball? Defend your answer.

To determine

The ball which will have the greater acceleration rolling down an incline- a bowling ball or a volleyball.

Answer to Problem 28A

Bowling ball

Explanation of Solution

Introduction:

The more the distance of the mass’s concentration from the axis of rotation, the more is the rotational inertia of the object.

The volleyball is majorly filled with air, then the rotational inertia of the volleyball will be obviously lesser than that of the bowling ball.

And, it is known that the greater the rotational inertia of an object, the more acceleration it has while rolling down an incline.

Conclusion:

Hence, the bowling ball will have more acceleration than the volleyball while rolling down an incline.
