(part 1 of 2)
A neutron in a reactor makes an elastic head-
on collision with the nucleus of an atom ini-
tially at rest.
Assume: The mass of the atomic nucleus is
about 14.8 the mass of the neutron.
What fraction of the neutron's kinetic en-
ergy is transferred to the atomic nucleus?
(part 2 of 2)
If the initial kinetic energy of the neutron is 7.93x10^-13 J, find its final kinetic energy. Answer in units of J.
