An optical disk drive in your computer can spin a disk up to 10,000 rpm (about 1045 rad/s). If a particular disk is spun at 880.7 rad/s while it is being read, and then is allowed to come to rest over 0.368 seconds,   what is the magnitude of the average angular acceleration of the disk? average angular acceleration:      rads2   If the disk is 0.12 m in diameter, what is the magnitude of the tangential acceleration of a point 1/9 of the way out from the center of the disk? tangential acceleration:       ms2
