a 7500 kg railroad car traveling at a speed of 26.0 m/s strikes a 5000kg car traveling at 10.0m/s. If the cars lock together as a result of collision what is their common speed afterward? How much of the initial kinetic energy is transferred to other forms of energy?

Answer in 3 decimal places, and include full equation please
