Problem 20Q

Problem

A block is given a brief push so that it slides up a ramp. After the block reaches its highest point, it slides back down, but the magnitude of its acceleration is less on the descent than on the ascent. Why?

Step-by-Step Solution:

Solution 20Q: There is difference in the magnitude of acceleration during descent and ascent motion due to frictional forces which changes its direction depending upon the direction of motion. Step 1 of 4 Concept: Frictional force also acts on the surface of the bodies in contact whenever their is relative motion between between the two bodies.
