The drive motor of a particular CD player is controlled to rotate at a speed of 190rpm when reading a track 5.7 cenitmeters from the center of the CD. The speed of the drive motor must vary so that the reading of the data occurs at a consant 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. ANSWER = 380(pi) per minute- no help needed b.) Find the linear speed. ANSWER 113.4 cm/sec- no help needed *****C.) Find the angualr speed (rpm) of the drive motor when it is reading a track 3 cm from the center of the CD. NEED HELP ON THIS ONE program says answer is 361rpm
