What is the ratio (K_{1} / K_{2}) when (K_{1}) is the kinetic energy converted to internal energy
Question:
What is the ratio \(K_{1} / K_{2}\) when \(K_{1}\) is the kinetic energy converted to internal energy when two cars each initially traveling ar \(88 \mathrm{~km} / \mathrm{h}\) collide head-on and \(K_{2}\) is the kinetic energy converted to internal energy when a car moving at \(88 \mathrm{~km} / \mathrm{h}\) hits a stationary car? Assume that both cars have the same inertia and that the collisions are totally inelastic. (Determine how much of the energy is required to move the center of mass in each case.)
