A rigid body acquires angular speed of 1...

A rigid body acquires angular speed of 100 rad `s^(-1)` after undergoing angular displacement of 600 rad in 12 s. Then the initial angular speed is ……… rad/s

A

`8.33`

B

100

C

0

D

50

Text Solution

Verified by Experts

The correct Answer is:
C

`theta=((omega+omega_(0))/(2))t`
`therefore 600=((100+omega_(0))/(2))12`
`therefore 100=100+omega_(0)`
`therefore omega_(0)=0`
