63. REASONINGAccording to Newton’s second law, the acceleration has the same direction as the net force and a magnitude given by a= ΣF/m. SOLUTIONSince the two forces are perpendicular, the magnitude of the net force is given by the Pythagorean theorem as ()2240.0 N60.0 NFΣ=+. Thus, according to Newton’s second law, the magnitude of the acceleration is
