Given information

Given:

A position-time graph.

 

Step-by-step explanation

Step 1.

The slope of a position-time graph can be used to calculate velocity. The steepest part of the slope shows that the velocity is at its highest. Small velocity is indicated by a time when the slope is not steep. The velocity of a straight horizontal line is zero.

Between 35 and 40 seconds, the slope is practically straight. As a result, the velocity in that period is zero.

The velocity is zero between 35 s to 40 s.
