A collision between two protons produces three new particles: p + p --->p + + + 0 + 0. The rest energies of the new particles are + (139.6 MeV), 0 (1116 MeV), 0 (497.7 MeV). Note that one proton disappears during the reaction. How much of the protons' incident energy (in MeV) is transformed into matter during this reaction?
