Determine the fraction of the magnitude of kinetic energy lost by a neutron (m1 = 1.01 u) when it collides head-on and elastically with a target particle at rest which is 21h (heavy hydrogen, m = 2.01 u).

Describe how the motion of a spring being pushed forward and backward is similar to the motion of air particles in a sound wave.
