Solution to task 657 from Chertov´s for extramural stud

657. During fission of uranium 235U nucleus under the action of a delayed neutron, fragments with mass numbers M1 = 90 and M2 = 143 were formed. Determine the number of neutrons emitted from the nucleus in this fission act. Determine the energy and speed of each of the fragments, if they fly away in opposite directions and their total kinetic energy T is equal to 160 MeV.
