A cyclist moving a car circular track of raidus 40 cm completes half a revolution in 40 s. Its average velocity is

A

zero

B

`4 pi ms^(-1)`

C

`2 cm s^(-1)`

D

`8 pi m s^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
Average velocity = Displacement / Time taken
`= (2R)/t = 2 xx 40/40 = 2 m s^(-1)`
