Question

A body rotates about a fixed axis with an angular acceleration `1rad//s^(2)` through what angle does it rotates during the time in which its angular velocity increases from `5rad//s` to `15rad//s`?

Answer 1

`omega^(2)=omega_(0)^(2)+2alphatheta`
`thereforetheta=(omega^(2)-omega_(0)^(2))/(2alpha)=(225-25)/(2xx1)`
`=100rad`
