Take the common case where an object of inertia \(m_{1}\) collides totally inelastically with a stationary object of inertia \(m_{2}\). Show that the fraction of kinetic energy converted in the collision is \(m_{2} /\left(m_{1}+m_{2}\right)\). Comment on the amount of energy converted for the cases \(m_{2} \gg m_{1}\). and \(m_{2} \ll m_{1}\).
