A disk is rotating with a constant angular speed of 18 rad/sec. At some instant the disk begins to experience a constant friction resulting in an angular acceleration of 1.4 rad/sec^2.

Find:

(a) the time (in sec) it takes the disk to come to a complete stop due to friction.

(b) total number of complete revolutions the disk undergoes before coming to a complete stop due to friction.

(c) the time (in sec) it takes the disk to complete 8 full revolutions.
