A neutron with mass m makes a head-on, elastic collision with a nucleus of mass M, which is initially at rest. (a) Show that if the neutron's initial kinetic energy is K, the kinetic energy that it loses during the collision is 4mMKoI (M + my
(b) For what value of M does the incident neutron lose the most energy?
(c) When M has the value calculated in part (b), what is the speed of the neutron after the collision?
