A neutron in a reactor makes an elastic head-on collision with the nucleus of an atom initially at rest.
Assume: The mass of the atomic nucleus is
about 12.4 the mass of the neutron.
What fraction of the neutron’s kinetic energy is transferred to the atomic nucleus?

If the initial kinetic energy of the neutron is
5.53 × 10−13 J, find its final kinetic energy.
Answer in units of J.
