Question

a cyclist moving on a circular track of radius 14m complete revolution in 11sec . what is his I average speed (ii) average velocity in One full revolution

Answer 1

Answer:

1) 28π / 11

2) 0

Explanation:

1) Perimeter of a circle of radius r is 2πr.

  So perimeter or distance of that circular path = 28π m

  Time = 11s

  Average speed = $\frac{Total Distance}{Time Taken}$

2) Average Velocity = Total Displacement / Time Taken

   = 0 / 11 = 0
