Distance, Displacement & Average Speed

A car runs at a constant speed on a circular track of radius 100 m, taking 62.8 seconds for every circular lap. The average velocity and average speed for each circular lap respectively is

Show answer and solution

Answer: (c)

After one full lap the car returns to the start: displacement $= 0$ , so average velocity $= 0$ .
Average speed $= \frac{2\pi R}{T} = \frac{2 \times 3.14 \times 100}{62.8} = 10$ m/s
So the answer is (c) 0, 10 m/s.
