You push on a rectangular door at the location of the knob (see diagram for top view). The door s mass is 63.0 kg, and its side-to-side width is 2.08 m. The knob is located 0.16 m from the right-hand side of the door. If you push with a force of 136 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.) 1.15 rad/s^2 4.59 rad/s^2 0.69 rad/s^2 2.87 rad/s^2
