A disk with the radius 0.60 m begins at rest and is then spun up to a high speed by applying an angular acceleration of 0.25 rad/s^2 for 20 seconds. The disk then revolves at a constant rate.
a. How long will it take for the disk to complete its first full revolution?
b. What is the final angular velocity of the disk?
c. What are the final velocity and acceleration of a point at the edge of the disk?
d. When the disk is revolving at a constant rate (after 20 seconds), how long will it take to complete a full revolution?
