When a motor cyclist takes a `U-turn` in `4s` what is the average angular velocity of the motor cyclist.

A

`pi//2 rad//s`

B

`pi//4 rad//s`

C

`pi//3 rad//s`

D

`pi//5 rad//s`

Text Solution

Verified by Experts

The correct Answer is:
B
`(T_(1))/(2)=4" "therefore T=8s`
`omega=(2pi)/(T)=(2pi)/8=(pi)/(4)`
