5. A copper rod is sliding on two conducting rails that make an angle of 17° with respect to each other, as in the drawing. The rod is moving to the right with a constant speed of 0.78 m/s. A 0.25-T uniform magnetic field is perpendicular to the plane of the paper. Determine the magnitude of the average emf induced in the triangle ABC during the 5.40-s period after the rod has passed point A.
