The nucleus splits into two fragments with a known mass ratio and total rest mass, and we need to calculate the kinetic energy of the more massive fragment using both relativistic and classical mechanics. The goal is to find the difference between these two kinetic energy values, which will help illustrate the significance of relativistic effects in nuclear processes."}
