Question

Problem 20

Answer 1

Given information

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.

 

Step-by-step explanation

Step 1.

Descent is the gain in negative altitude and ascent is the gain in positive altitude. It means both are opposite to each other.

When the block is moving up then the gravitational force and the frictional force are parallel and act together.
