Okay,but my another argument is that if we say kinetic energy is ##\frac {p²} {2m}## and if kinetic energy of centre of mass changes then also momentum should be changed.
The kinetic energy of a two body system is not determined by the "kinetic energy of the center of mass" (whatever that means). The kinetic energy of a two body system is the sum of the kinetic energies of each of the bodies separately.
