A 30.0 cm diameter turntable platter of a record player is attached, by a belt (to reduce vibrations) to a motor-driven pulley 2.0 cm in diameter.

1. Determine the platter's angular acceleration if it is to reach 33 1/3 rpm in 6.0 s.
2. How many rotations will the platter make before reaching operating speed?
3. How many rotations will the pulley make before reaching operating speed?
