Suppose a moving hydrogen atmo makes a head on inelastic collision with a stationary hydrogen atmo. Before collision both atoms are in ground state and after collision they move together. What is the minimum velocity of the moving hydrogen atom if one of the atom is to be given the minimum excitation energy after the collision ? `(m_(H) = 1.0078 am u, 1 am u = 1.66 xx 10^(-27) kg)`
