A disc rotates about a fixed axis with an initial angular velocity of 5.0 rad/s counterclockwise. Upon completing 2 revolutions, the disc has an angular velocity of 2.5 rad/s. (a) Find the angular acceleration of the disc. (Ans : -0.75 rad/s2 ) (b) Calculate the time taken by the disc to complete the 2 revolutions. (Ans : 3.33 s)(c) If the disc maintains the same constant angular acceleration until it reaches 2.5 rad/s clockwise, sketch the graph of angular velocity versus time from 5.0 rad/s counterclockwise to 2.5 rad/s clockwise.
