An optical disk drive in a computer can spin a disk at up to 10,000 rpm. If a particular disk is spun at 2250 rpm while it is being read, and then is allowed to come to rest over 0.301 s, what is the magnitude of the average angular acceleration of the disk? angular acceleration: 782.79 rad/s? If the disk is 12.0 cm in diameter, what is the magnitude of the tangential linear acceleration of a point 1/11 of the way out from the center of the disk? linear acceleration: m/s?
