You push on a rectangular door at the location of the knob (see diagram for top view). The door s mass is 72.8 kg, and its side-to-side width is 1.65 m. The knob is located 0.15 m from the right-hand side of the door. If you push with a force of 133 N, what will the be the door s angular acceleration as it swings on its hinges? (Note: the moment of inertia of the door of mass M and width x, swinging on its hinges, is (1/3) M x^2.)
