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 822.1 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? rad average angular acceleration: 2234 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? 148.93 tangential acceleration: Incorrect

Angular speed, acceleration and displacement
Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.
Angular Position
Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.
