A car runs at a constant speed on a circular track of radius , taking for every circular lap. The average velocity and average speed for each circular lap respectively is:
Step 1: Given
Radius of the track,
Step 2: Formula used
Step 3: Determine the average velocity
As the track is circular, the total displacement will be zero.
Displacement is the shortest distance covered. And in the case of a circular path, the initial and final points coincide. Hence, the shortest distance will be zero.
Step 4: Determine the average speed
The distance covered will be the circumference of the track.
Hence, option B is the correct option.
