Question

The $v-t$ plot of a moving object is shown in the figure. The average velocity of the object during the first $10\text{seconds}$ is

• A. $0$
• B. $2.5\text{ms}$
• C. $5\text{ms}$
• D. $2\text{ms}$

Answer 1

The correct option is A $0$

We know that
Average velocity = $\frac{\text{Total displacement}}{\text{Total time}}$
For 10 seconds, the area under the v-t curve is zero, the total displacement is zero.
Hence the average velocity is zero.
