An atom of U238 spontaneously decays into two components. One is a small fragment that is ejected with a speed of 1.50x107 m/s and a larger "daughter" nucleus that recoils with a measured speed of 2.56x105 m/s. After the disintegration, the fission products move in opposite directions. If all masses are to be measured in atomic mass units (mass the of U nucleus being 238 au), what are the masses of the fission products.
