A steel ball bearing (m =50.0g) is launched with a velocity of 40.0m/s toward a ball of silly putty (m=0.500kg) at rest on a frictionless surface.They collide inelastically, they undergo a second collision with a larger steel ball bearing (m=200.0 g). The second collision is elastic.what is the final velocity of the larger steel ball?
