Homework Help: Finding angular acceleration from revolutions and velocity

  1. Feb 8, 2017 #1
    1. The problem statement, all variables and given/known data
    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.

    2. Relevant equations

    3. 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:
    I'm not given the answer for this question so I am not sure if I am right or extremely wrong
