A magnetic computer 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:
600m rads / (s^2),
then coasts at a steady angular velocity for another (1/2) s
What is the speed of the dot at t = 1.0 s?
Through how many revolutions has it turned?
