Just had a general question involving the change in Kinetic Energy in a Inelastic collision between 2 cars going towards each other at equal velocity.(adsbygoogle = window.adsbygoogle || []).push({});

ΔK = K - K_{o}

However for the final K, is the mass the combined mass of both cars since they are now moving together, or is it still the same mass as before the collision?
