The speed of a body moving in a circle of radius 15 cm changes from ` 180 rev//min to 600 rev //min "in" 11 s` . Then the angular acceleration of the body will be

A

`1 rad//s^(2)`

B

`2 rad//s^(2)`

C

`3 rad //s^(2)`

D

`4 rad//s^(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`alpha=(omega_(2)-omega_(1))/(t)=(2pi(n_(2)-n_(1)))/(t)`
