1. The problem statement, all variables and given/known data Two cars collide as both are traveling at 90km/hr. What is the increase in temperature of the wrecks, assuming that the cars have c = 447 joules/kelvin. 2. Relevant equations Q= mc(change in T) 3. The attempt at a solution I found the joules of kinetic energy equal to 625 joules * mass of car (25 m/s speed = 625/2 joules of KE per car X two cars). I then divided that by 447 for the c value, to get 1.4 K. But the answer is not correct?
