Angular acceleration Definition and 552 Threads

How do you find angular acceleration when all you have is angular and linear velocity and a radius of a circle? I tried to use the kinematics but all of them require time or theta.

A rotating wheel requires 2.93 s to complete 37.0 revolutions. Its angular speed at the end of the 2.93 s interval is 97.1 rad/s. What is the constant angular acceleration of the wheel? I know this should be easy. I'm just missing something. I figured 37 rev = 232 rad (=theta). Then I used...
