A disk rotates with constant angular acceleration. The initial angular speed of the disk is 2rad/s. After the disk rotates through 3radians, the angular speed is 10rad/s.

1. What is the magnitude of the angular acceleration?

2. How much time did it take for the disk to rotate during 3 pi radians?

3. What is the tangential acceleration of a point located at a distance of 4.8 cm from the center of the disk?
