Because or air resistance and to keep the ball moving at constant speed, a continual push must be exerted on the stick, causing a 0.036 N • m torque. Determine the magnitude of the resistive force that the air exerts on the ball opposing its motion. What assumptions did you make?

- As a compact disc (CD) spins clockwise as seen from above,information is read from it, starting with the innermost ring andmoving outward. When the information is being read from theinnermost ring, the CDs angular speed is 0 = 52.4 rad /s. TheCD slows down so that when information is read from the outermost ring, = 20.9 rad /s. It takes 74 min 33 s to read themusic from a particular CD.

How does the angular speed v of the disk at point H compare with the angular speed of the disk at point R? b.
