Question

Give an example of motion in which average speed is not zero, but the average velocity is zero.

• A. A car moving with an average speed returns to the initial position
• B. A car at rest
• C. A car with non zero displacement.
• D. All of the above.

Answer 1

The correct option is A A car moving with an average speed returns to the initial position

Suppose a car covers a distance of 50 m in 5 seconds and comes back to initial position in 5 seconds. The average speed of car is 10 m/s, but average velocity is zero because displacement is zero.
