5. A potter spins a circular clay disc of radius 0.20 m on a turntable. The disc starts from rest and is given a constant angular acceleration of 6.0 rad s−2 for 4.0 s. It is then allowed to rotate at the attained constant angular speed for an additional 10 s.
(i) Calculate the angular speed of the disc at t=4.0s.
(ii) Determine the angular displacement during the first 4.0 s.
(iii) Find the total linear distance travelled by a point on the rim in the entire 14 s interval.
(iv) Express the total number of complete revolutions made by the disc in these 14 s.
