Three identical small spheres, each of weight 2 lb, can slide freely on a horizontal frictionless surface. Spheres B and C are connected by a light rod and are at rest in the position shown when sphere B is struck squarely by sphere A which is moving to the right with a velocity V₁ = (8 ft/s)i. Knowing that 0 = 45° and that the velocities of spheres A and B immediately after the impact are VA = 0 and VB = (6 ft/s)i + (VB)y j, determine (VB)y and the velocity of C immediately after impact.
