A disk with a radial line painted on it is mounted on an axle perpendicular to it and running through its center. It is initially at rest, with the line at q0 = -90.0°. The disk then undergoes constant angular acceleration. After accelerating for 3.15 s, the reference line has been moved part way around the circle (in a counterclockwise direction) to qf = 130°.

Given this information, what is the angular speed of the disk after it has traveled one complete revolution (when it returns to its original position at -90.0°)?

2. Relevant equations

3. The attempt at a solution

Not sure I know have to use Rotational Kinematics to find the angular velocity first.
