Neglecting friction, a small and a large block of ice begin sliding down an incline together. The larger block reaches the bottom
A)before the small block.
B)after the small block.
C)at the same time as the small block.

Question

Quizplus · Accepted Answer

Neglecting friction means that both blocks will experience the same acceleration down the incline. The time it takes for an object to slide down an incline depends only on its acceleration and vertical displacement. Since both blocks start at the same height and experience the same acceleration, they will take the same amount of time to reach the bottom. Therefore, the larger block and the smaller block will reach the bottom at the same time.
