Perhaps you are not familiar with nerf balls. Nerf balls are foam

ball it stops and the nerf ball just quivers a bit. The center of
mas quits moving. The kinetic energy of the cue ball has been
converted to heat. Energy is conserved, momentum is not.

There is more to that. If this collision occurs in outer space, I
guarantee you that the center of mass will =not= quit moving.

But it will not move in a manner that conserves momentum.

You really need to study basic physics...
