## Homework Statement

an object starts from rest and has a final angular velocity of 6 rad/s. the object makes 2 complete revolutions. find the object's angular acceleration.

## Homework Equations

wf^2=wi^2+2αd

## The Attempt at a Solution

Not sure what to do with the revolutions, would it take act as the distance traveled? I am not given the radius, so the most I can do is:

6^2=0+2α(2rev*2π)

α=1.43rad/s^2

I'm not given the answer for this question so I am not sure if I am right or extremely wrong
