When the power is turned off on a turntable spinning at 71.0 rpm , you find that it takes 12.6 revolutions for it to stop while slowing down at a uniform rate.
Part A What is the angular acceleration (in rad/s^2 ), of this turntable?
Part B How long does it take to stop after the power is turned off?
