A disk rotates around its central axis beginning from rest and accelerates with constant angular acceleration. At one time it is rotating at 11 rev/s. 65 revolutions later; its angular speed is around 24 rev/s.
(i) Compute the angular acceleration.
(ii) Compute the time needed to complete the 65 revolutions mentioned.
(iii) Compute the time needed to achieve the 11 rev/s angular speed.
