Problem

A 1500 kg1500\,\text{kg} car moving at 12 m s−112\,\text{m}\,\text{s}^{-1} rear-ends a 1200 kg1200\,\text{kg} car at rest. The cars lock together and move as one after the impact. Calculate the percentage of the initial kinetic energy that is converted to other forms and identify the collision type.
