A neutron having kinetic energy `12.5eV` collides with a hydrogen atom at rest negect the difference in mass between the neutron and the hydrogen atom and assume that the neutron does not leave its of motion find the posible kinetic energy of the neutron after the event

A free hydrogen atom in its ground state is at rest. A neutron having kinetic energy k_(0) collides head one with the atom. Assume that mass of both neutron and the atom is same. (a) Find minimum value of k_(0) so that this collision can be inelastic. (b) If k_(0) = 25 eV , find the kinetic energy of neutron after collision if its excites the hydrogen atom to its second excited state. Take ionization energy of hydrogen atom in ground state to be 13.6 eV .

A neutron collided elastically with the nucleus of the a carbon atom at rest . Show that the neutron lost 0.284 part of its initial kinetic energy .
