Problem
A ceiling fan is switched on from rest and attains a constant angular acceleration of 2rad s−2 that lasts for 8s. Answer the following.
(i) Calculate the angular displacement of the fan blades during this interval in radians.
(ii) Express the result of part (i) in the number of complete revolutions made.
(iii) Determine the final angular speed attained at the end of 8s.
