a) A student hangs three masses from a force table. If the first mass of 178 g is at an angle of 194°, and she then hangs a mass of 228 g at 249°, calculate the mass and angle of the third mass 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 the attached sheet of graph paper, represent the vectors from part a) graphically and to scale. Each square on the graph paper is 25 g.

1. **a)** A student hangs three masses from a force table. If the first mass of 178 g is at an angle of 194°, and she then hangs a mass of 228 g at 249°, calculate the mass and angle of the third mass 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 the attached sheet of graph paper, represent the vectors from part a) graphically *and to scale*. Each square on the graph paper is 25 g.
