A wheel has a maximum rate of rotation of 150 revolutions per minute. Starting from rest, and accelerating at a constant rate, the wheel took 20 seconds to reach its maximum angular speed.
(i) Calculate the magnitude of its angular acceleration.
(ii) Calculate the number of revolutions made by the wheel during this process.
