The flywheel of a steam engine begins to rotate from rest with a constant angular acceleration of 1.45 rad/s2. It accelerates for 29.5 s, then maintains a constant angular velocity. Calculate the total angle through which the wheel has turned 63.7 s after it begins rotating.

Answer 1

d = 0.5a*t^2 = 0.725 * 63.7^2 = 2942 Rad
