A) It takes the lighter object 5 times longer to reach the bottom of the incline than the heavier.
B) It takes the lighter object 10 times longer to reach the bottom of the incline than the heavier.
C) It takes the heavier object 5 times longer to reach the bottom of the incline than the lighter.
D) It takes the heavier object 10 times longer to reach the bottom of the incline than the lighter.
E) The two objects reach the bottom of the incline at the same time.

Question

Quizplus · Accepted Answer

On a frictionless inclined plane, the acceleration of an object is independent of its mass. Therefore, both objects will reach the bottom at the same time.
