a) A student hangs a mass of 150 g on a force table at an angle of 150°. If she then hangs a mass of 220 g at 270°, at what angle should she hang a mass of 195 g so that the ring on the force table is in equilibrium? For maximum credit, show your work. Assume the given masses include the mass of the hangers.
b) On a separate sheet of graph paper, represent the vectors from part a) graphically and to scale.
