A moving body of mass m makes a head on elastic collision with another body of mass `2m` which is initially at rest. Find the fraction of kinetic energy lost by the colliding particles after collision.

A moving particle of mass m makes a head-on perfectly inelastic collision with a particle of mas 2m which is initially at rest. Find the fractional loss in energy of the colliding partic le after collision.
