   Yes I hear you. It is not absolutely momentum conservation or absolutely   
   center of mass conservation. They both work so why draw a line between   
   the two.   
      
   On another note what about one of the masses radioactively decaying   
   losing mass but not violating the conservation of momentum as stated   
   before. It is a tricky problem with no easy answers that I can think   
   of. Ears open if you have a fix.
