Two 800-kg cars moving at a velocity of 90 km/h have a head-on collision on a road. Both
cars come to a complete rest after the crash. Assuming all the kinetic energy of cars is
converted to thermal energy, determine the average temperature rise of the remains of
the cars immediately after the crash. Take the average specific heat of the cars to be 0.45
kJ/kg · °C.
