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?

  • physics - ,

    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?

  • physics - ,

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

  • physics - ,

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