The balance wheel of a watch vibrates with an angualr amplitude `pi` radians and a period of 0.5s. Find a) the maximum angular speed of the wheel, b) the angular speed of the wheel when its displacement is `pi/2` radians and c) the angular acceleration of the wheel when its displacement is `pi/4` radians.
[hint: use formulae of linear SHM for the angular SHM of the wheel]
