Physics

Starting from rest, a disk rotates about its central axis withconstant angular acceleration. In 4.00 s, it rotates 13.2 rad.During that time, what are the magnitudes of (a) the angularacceleration and (b) the average angular velocity? (c) What is theinstantaneous angular velocity of the disk at the end of the 4.00s? (d) With the angular acceleration unchanged, through whatadditional angle (rad) will the disk turn during the next 4.00s?
