1. The problem statement, all variables and given/known data The flywheel of a steam engine begins to rotate from rest with a constant angular acceleration of 1.35 rad/s^2. It accelerates for 33.1 s, then maintains a constant angular velocity. Calculate the total angle through which the wheel has turned 47.5 s after it begins rotating. 2. Relevant equations 1. w=wi +alpha(time) 2. theta - theta(initial) = 1/2(w +wi)t 3. The attempt at a solution I have attempted this problem several times and keep getting the answer wrong!!! (note: I do not know the correct answer for this particular problem) First I used equation 1 to find the constant angular velocity. Then, since I know that constant velocity means zero acceleration, I used equation 2 to find the total angle. What am I doing wrong? Please help!
