A computer hard disk 8.0 cm in diameter is initially at rest. A small dot is painted

Question:

A computer hard disk 8.0 cm in diameter is initially at rest. A small dot is painted on the edge of the disk. The disk accelerates at 600 rad / s² for 12 s, then coasts at a steady angular velocity for another ½ s.

a. What is the speed of the dot at t = 1.0 s?

b. Through how many revolutions has the disk turned?
