Consider the two points B(2,4) and C(-1,-5) in the xy-plane. The coordinates are given in meters. A 20-N force is applied at point B at 120 degrees counterclockwise from the positive direction of the x-axis (where positive direction is horizontal to the right). Note that the force vector is also in the xy-plane (2D case). What is the magnitude of the moment of this force about point C?
