A circular disk starts from rest and spins around its central axis until it reaches 10 rad/s in 30 seconds at a constant angular acceleration. What is the angular acceleration?

Divide the final angular velocity (10 rad/s) by the time required to accelerate to that value (30 s). The dimensions of the answer will be rad/s^2
