Find the angular speed of the reel when the spring is again unstretched. (Answer using theta for è, g for the acceleration due to gravity, and R, I, m, k, and d, as necessary.)

((2mgsin(theta)-kd^2)/I)^(1/2) is what I got when I tried to solve it, but it's not right. I started with mgsin(theta) = (1/2)kd^2 + (1/2)Iw^2 to get there. Where did I go wrong?
