It is possible to predict the subsequent motion of two point masses after a linear collision using their mass and velocity before the collision, assuming no energy is lost and the masses are equal. In a billiards context, this prediction holds true under ideal conditions. However, the challenge arises from the uncertainty of the energy status of the system post-collision. Accurate predictions require knowledge of energy conservation and the collision dynamics. Overall, while predictions can be made under specific assumptions, real-world factors may complicate the outcomes.
