Question

Starting from A, Paheli moves along a rectangular path ABCD as shown in Figure 13.7. She takes 2 minutes to travel each side. Plot a distance-time graph and explain whether the motion is uniform or non-uniform.

Short Note

Solution

Since the distance covered per unit time for the entire rectangular path covered is not the same, the motion is non-uniform.
