Question

Quizplus · Accepted Answer

Both objects will experience the same acceleration due to gravity down the incline. However, the ring has a larger radius and therefore will have a greater moment of inertia. This means it will be more resistant to rotational motion, causing it to roll more slowly down the incline compared to the coin which has a smaller moment of inertia. Therefore, the coin will reach the bottom of the incline first.
