When a radioactive nucleus of astatine 215 decays at rest, the whole atom is torn into two in the reaction
The masses of the three atoms are (in order) 214.9986, 210.9873, and 4.0026, all in atomic mass units. (1 atomic mass unit = 1.66 x 10-27kg = 931.5 MeV/c2.) What is the total kinetic energy of the two out coming atoms, in joules and in MeV?
