Three forces act on a moving object. One force has a magnitude of 78.6 N and is directed due north. Another has a magnitude of 55.3 N and is directed due west. What must be (a) the magnitude and (b) the direction of the third force, such that the object continues to move with a constant velocity? Express your answer as a positive angle south of east.
