A disk rotates about its central axis starting from rest and accelerates with constant angular acceleration At one instant it is rotating at 12 rad/s and after 80 radian of more angular displacement. its angular speed becomes 28 rad/s. How much time (seconds) does the disk takes to complete the mentioned angular displacement of 80 radians.
