A rotating disk is initially spinning at w = 6rev / s , slows down and stops in 19.7 . What is the magnitude of the disk's average angular acceleration? (in rev/s^ ^ 2)

An optical disk drive in a computer can spin a disk at up to 10,000 rpm. If a particular disk is spun at 6170 rpm while it is being read, and then is allowed to come to rest over 0.368 s, what is the magnitude of the average angular acceleration of the disk?

A wheel of 1.00 m radius turns as 253 rpm. Recall 1 revolurion = 2pi radius, and 1minute = 60.0s secondsFind the angular velocity in rad/s?

A disk of radius R-37.3cm rotates about its central axis through O with a constant angular acceleration X =1.05rad/s2, as shown in the figure. At t 0, the initial tangential speed of a point P on the rim of the disk is Vo-12.64m/s. Find the final tangential speed v of the point P at any time t-17s. Express your answer using one decimal place.
