Three particles are sliding along a flat frictionless surface, Ma = 0.4 kg, Mb = 0.5 kg, and Mc = 0.4 kg. Before any colisions take place, Va = 15 i m/s, Vb = 10 i m/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? Distance between a and b is r = 2i m and distance between b and c is r = 15i m. Assume that a strikes b before b strikes c.
