Problem
A turntable starts from rest and rotates about its fixed vertical axis with uniform angular acceleration. In the first 4.0s it completes 5.0 revolutions.
(i) Express the angular displacement completed in this interval in radians.
(ii) Calculate the angular acceleration of the turntable.
(iii) Determine the angular speed of the turntable at the end of 4.0s.
(iv) How many additional revolutions will the turntable complete in the next 2.0s if the angular acceleration remains unchanged?
