As you finish listening to your favorite compact disc (CD), the CD in the player slows down to a stop. Assume that the CD spins down with a constant angular acceleration. If the CD rotates clockwise at 500 rpm (revolutions per minute) while the last song is playing, and then spins down to zero angular speed in 2.60 s with constant angular acceleration, what is α, the magnitude of the angular acceleration of the CD, as it spins to a stop? A grinding wheel 0.21 m in diameter rotates at 2600 rpm. What is the linear speed of a point on the edge of the grinding wheel? What is the acceleration of a point on the edge of the grinding wheel? A small rubber wheel is used to drive a large pottery wheel. The two wheels are mounted so that their circular edges touch. The small wheel has a radius of 1.7 cm and accelerates at the rate of 6.9 rad/s2 , and it is in contact with the pottery wheel (radius 28.0 cm ) without slipping. Calculate the angular acceleration of the pottery wheel. Calculate the time it takes the pottery wheel to reach its required speed of 57 rpm .
