Answer #1

A)

Torque, T = r x F

T = 58.5 x (1.5/2) = 43.88 Nm

B)

Torque, T = 58.5 x 1.5 = 87.75 Nm

    A student opens a 12.0 kg door by applying a constant force of 40.0 N at a perpendicular distance of 0.900 m from the hinges. If the door is 2.00 m in height and 1.00 m wide, what is the magnitude of the angular acceleration of the door? (Assume that the door rotates freely on its hinges.) The moment of inertia for a door about the hinge is I = -mr2.
