The flywheel of a steam engine begins to rotate from rest with a constant angular acceleration of 1.41 rad/s2. It accelerates for 25.5 s, then maintains a constant angular velocity. Calculate the total angle through which the wheel has turned 65.5 s after it begins rotating.

V = a*t = 1.41 * 25.5 = 35.96 rad/s.

d=V*t = 35.96 * (65.5-25.5) = 1438 rad.
