O out of 15 poin A vertical rectangular object of uniform mass M-13.7kg has sides a=0.7m and b-2m. It is pivoted from point O as shown in the figure below. If a constant force of F=78N along the diagonal as shown is applied, determine the angular acceleration of the rectangle at the instant shown in the figure using SI units. Express your answer with two decimal places. Please use the convention: Clockwise (+), Counterclockwise (-) when expressing your answer. Hint1: The moment of inertia of the rectangle about an axis of rotation passing through its center of mass is 12 I want to know the working from a previous exam Hint2: Don't forget the force of gravity!!! Take g=9.80 m/s². F СМ a 0. b
