## Homework Statement

A wheel rotating about a fixed axis with a constant angular acceleration of 2.0 rad/s

^{2}turns through 2.165 revolutions during a 2.0 s time interval. What is the angular velocity at the end of this time interval?

## Homework Equations

I was using the kinematic Equations

[itex]\theta[/itex]

_{f}= [itex]\theta[/itex]

_{i}+ [itex]\omega[/itex]

_{i}t + 0.5[itex]\alpha[/itex]t

^{2}

Am i doing something wrong?

The answers that I can choose are, 9.7 rad/s, 9.1 rad/s, 9.3 rad/s, 9.5 rad/s, 8.8 rad/s

All the answers I get are way larger

I must be doing something obviously wrong but I just cant see it.
