016 (part 1 of 2) 10.0 points
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 11.8 the mass of the neutron.
what fraction of the neutron's kinetic en-
ergy is transferred to the atomic nucleus?
017 (part 2 of 2) 10.0 points
if the initial kinetic energy of the neutron is
2.72 x 10-1 j, find its final kinetic energy.
answer in units of j.
