Question

A car travels 1 km and returns to the same point in a different path. What is its average velocity?

• A. $0m{s}^{-1}$
• B. $1m{s}^{-1}$
• C. $3m{s}^{-1}$
• D. data insufficient

Answer 1

The correct option is A $0m{s}^{-1}$

Average velocity $=\frac{\text{Total displacement}}{\text{Total time}}$

Since, in this case, the particle initial and final points are the same, therefore its Displacement $=0$.

$\therefore$ Average velocity = 0
