A person pushes on a doorknob with a force of 5.00 N. The direction of the force is at an angle of 20.0° from the perpendicular to the surface of the door. The doorknob is located 0.800 m from axis of the hinges of the door. The door begins to rotate with an angular acceleration of 2.00 rad/s2. What is the moment of inertia of the door about the hinges?
A) 4.28 kg∙m2
B) 7.52 kg∙m2
C) 1.88 kg∙m2
D) 0.684 kg∙m2
E) 2.74 kg∙m2
