Question

Is the particle in Fig. 1.3 speeding up? Slowing down? Or can you tell? Explain.

Short answer

Speed is defined as the rate of change of distance over time.

Step-by-step solution

Given information:

There are five dots given in the diagram.

Explanation for the problem:

• Since the number is not specified, one cannot find whether the object represented by the dot is either moving right to left or left to right.
• If the particle is moving from left to the right, it is slowing down.
• If the particle is moving from right to the left, it is speeding up.
