Problem
A potter’s wheel is rotating uniformly at 6rad s−1 when the potter gently presses a wet cloth on its rim, producing a constant angular deceleration that brings the wheel to rest in 5s.
(i) Find the magnitude and sign of the angular acceleration produced.
(ii) Calculate the total angular displacement made by the wheel before it comes to rest. Give your answer in both radians and complete revolutions.
(iii) Determine the time taken by the wheel to complete its last full revolution just before coming to rest.
