Three particles are sliding along a flat, frictionless surface. mA = 0.4 kg, mB = 0.5 kg, and mC = 0.4 kg. Before any collisions take place, vA = 15i m/s, vB = 10im/s, and vC = 5 m/s. e = 0.85 between A and B and e = 0.6 between B and C. How fast will ball C be traveling after all collisions have ceased? At the illustrated, pre-impact position shown, rB/A=2i m and rC/B= 15i m. Assume that A strikes B before B strikes C.
