Canadian nuclear reactors use heavy water moderators in which elastic collisions occur between the neutrons (mass
1.0u
) and deuterons of mass
2.0u
. Part 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 which is initially at rest? Express your answer using three decimal places.
(v_(2))/(v_(1))=
Request Answer Part B What is its kinetic energy, expressed as a fraction of its original kinetic energy? Express your answer using three decimal places. Request Answer Part C How many such successive collisions will reduce the speed of a neutron to

of its original value? Express your answer as a number of collisions.
