Homework Statement


A wheel rotating about a fixed axis with a constant angular acceleration of 2.0 rad/s2 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]it + 0.5[itex]\alpha[/itex]t2

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.
