6. The drive motor of a particular CD player is controlled to rotate at a speed of 200 rpm when reading a track 5.7 centimeters from the center of the CD. The speed of the drive motor must
vary so that the reading of data occurs at a constant rate.
a. Find the angular speed (in radians per minute) of the drive motor when it is reading a
track 5.7 centimeters from the center of the CD.
b. Find the linear speed (in cm/sec) of a point on the CD that is 5.7 centimeters from the
center of the CD.
C. Find the angular speed (in rpm) of the drive motor when it is reading a track 3
centimeters from the center of the CD. Remember the linear speed is the same for
both tracks.
