Two railroad cars, each of mass 6500kg and traveling 95km/h, collide head-on and come to rest. How much thermal energy is produced in this collision?

determine the initial Kinetic energy of each, and add. All that must be converted into heat, since the cars are at rest in the end, right?

yes b/c all energy is turned into heat, but what equation should i use?

m*V^2, remember to convert 95km/h to m/s
