The angular displacement (theta) of the ...

The angular displacement `(theta)` of the blades of a ceiling fan, when the fan is switched on at t=0, is shown in figure. The average angular velocity of the fan blades during the first 8 seconds will be

A

`40 pi rad//s`

B

`20pi rad//s`

C

`10pi rad//s`

D

`5pi rad//s`

Text Solution

Verified by Experts

The correct Answer is:
C
`(omega)=("angular displacement")/("time taken")=(80pi)/(8)=10pi rad//s`
