I did not get answers to any of last 5-6 question hope i get for this. Three spheres, each with a mass of m , can slide freely on a frictionless, horizontal surface. Spheres A and B are attached to an inextensible, inelastic cord with a length l and are at rest in the position shown when sphere B is struck squarely by sphere C , which is moving with a velocity v 0 . Knowing that the cord is taut when sphere B is struck by sphere C and assuming perfectly elastic impact between B and C , and thus the conservation of energy for the entire system, determine the velocity of each sphere immediately after impact.
