10. You push on a rectangular door at the location of the knob
(see diagram for top view). The door s mass is 69.2 kg, and its
side-to-side width is 1.74 m. The knob is located 0.12 m from the
right-hand side of the door. If you push with a force of 148 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.)
