A car runs at constant speed on a circular track of radius 100 m taking 62.8 s on each lap. What is the average speed and average velocity on each complete lap?
  • a)
    Velocity 10 m/s speed 10 m/s 
  • b)
    Velocity zero, speed 10 m/s
  • c)
    Velocity zero, speed zero
  • d)
    Velocity 10 m/s, speed zero
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
A car runs at constant speed on a circular track of radius 100 m takin...
Average speed = 2*pi*100/62.8 = 10 m/s
Average velocity = 0 m/s [since, displacement for each lap = 0]

After each lap done by the car, displacement = 0 m
And distance covered = 2r = 2 x 3.14 x 100 m
Thus avg. velocity = 0 and avg. speed = 628 / 62.8 = 10m/s
