A fly wheel starts rotating from rest and acquires rotational speed of 360 revolution s^(-1) in 3 minutes. The average angular acceleration is…………..

Answer»

`3("revolution")/(("second")^(2))`
`4("revolution")/(("second")^(2))`
`1("revolution")/(("second")^(2))`
`2("revolution")/(("second")^(2))`

SOLUTION :`ALPHA=(omega-omega_(0))/(t)=(360-0)/(3xx60)=2("revolution")/(("second")^(2))`
