Canadian nuclear reactors use heavy water moderators in which elastic collisions occur between the neutrons and deuterons of mass 2.0 u. (a) What is the speed of a neutron, expressed as a fraction of its original speed, after a head-on, elastic collision with a deuteron that is initially at rest? (b) What is its kinetic energy, expressed as a fraction of its original kinetic energy? (c) How many such successive collisions will reduce the speed of a neutron to 1/59,000 of its original value?

Question
Canadian nuclear reactors use heavy water
moderators in which elastic collisions occur between the neutrons and
deuterons of mass 2.0 u. (a) What
is the speed of a neutron, expressed as a fraction of its original speed,
after a head-on, elastic collision with a deuteron that is initially at rest?
(b) What is its kinetic energy, expressed as a fraction of its original kinetic
energy? (c) How many such successive collisions will reduce the
speed of a neutron to 1/59,000 of its original value?
