> A compact disc player rated as having speed of 8X will operate at an angular speed of about 4,000 rpm. a) What is the angular speed of the disc in the unit of radian/sec? b) By modelling the compact disc (CD) as a thin uniform disc with mass 10 g, an inner radius of 23 mm, and an outer radius of 58 mm, calculate the rotational inertia of the disc. c) If the torque provided by the motor rotate this disc has the magnitude of 0.1 N.m. What is the angular acceleration of the disk? d) For this angular acceleration, how many radians has the disc rotated, after 2 seconds? e) How many revolutions in (d) above?
