Problem
A potter’s wheel initially rotates clockwise at 8.0rads−1. Starting at t=0, it is brought to rotate anticlockwise at 8.0rads−1 in 6.0s under a uniform angular acceleration. Anticlockwise rotation is taken as positive.
(i) Write the initial and final angular velocities with proper signs.
(ii) Calculate the magnitude and sign of the uniform angular acceleration.
(iii) Find the angular displacement of the wheel during the 6.0s interval.
