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.
Q= mc(change in T)
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?
