Let's begin with the angular acceleration of a compact disk (CD). To play music the CD must rotate at high speed while a laser reads data encoded in a spiral pattern on the disk. The disc has radius R = 6.0 cm = 0.060 m; when data are being read, it spins at 7200 rev/min. What is the CD's angular velocity w in radians per second?
