Chapter 2.3, Problem 22SSC

To determine

The motion diagram by using given position-time graph.

Explanation of Solution

Introduction:

The velocity of the hockey puck is same as the slope of the given position-time graph. The slope of the position-time graph is linearly increasing, so the velocity of the hockey increases with the position.

The slope of the position-time graph describes the velocity of the object. As the slope of the given position-time graph is $20\text{m}/\text{s}$ . The speed of the object is constant, so the motion of the object is uniform motion. The motion diagram of the uniform motion of the object is a line parallel to time axis of the velocity-time graph and it is given below:
