Only problem here is that the heavy particle is NOT much larger than the light particle. Much heavier imply s a factor of at least 10. In your case likely a factor of 1000 or more. Also the collision is not totally inelastic in your case, because energy MUST be conserved. The lighter ball MUST end up going faster than the heavy ball. Your calcs are probably what a real item would do (elastic}, but we are dealing with ideal (inelastic) balls here.
Anyone can do the math, its the setup that separates the men from the boys.
