You push on a rectangular door at the location of the knob (see diagram for top view). The door s mass is 76.3 kg, and its side-to-side width is 1.78 m. The knob is located 0.10 m from the right-hand side of the door. If you push with a force of 168 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.) 3.50 rad/s^2 s 2 1.75 rad/s^2 3 4.90 rad/s^2 4 1.40 rad/s^2
