STANDARD Physics Circular Motion MCQ Question
A cyclist moving on a circular track to radius 40 m completes half a revolution in 40 s. Its average velocity is
Zero
4π m s⁻¹
2 m s⁻¹
8 π m s⁻¹
Correct Answer
Detailed Explanation
The average velocity is calculated as the displacement divided by the time taken. Since the cyclist completes half a revolution, the displacement is the diameter of the circle, which is 2R = 80 m. Thus, average velocity = 80 m / 40 s = 2 m s⁻¹.
