The moment of inertia of the door is given by I = 1/3 MW2, where M is the door's mass and W is the width of the door. Take W = 80.0 cm and M = 10.0 kg. For the door in the position shown in the figure: a) Calculate the torque applied by the door closing mechanism on the door; b) Calculate the angular acceleration of the door
