Rotational mechanics applied to the motion of a wheel

The wheel of a motor, accelerated uniformly from rest, rotates through 2.5 rad during the first second. Find the angle rotated during the next second.

Solution Preview

The angular acceleration is constant. Thus we have,
(we will use A for angular acceleration and z for the angle of rotation):

z = Wo x T + ...
