4.3 Accident A 1t car running at a speed of 200 km/h crashes against a concrete wall and comes to rest. Assume that the car is made of steel (p kg = 7830 m3, c = 0.5), and that all energy stays in the truck. kJ kgK a) By what amount will the average temperature of the car change? b) How much entropy is created in the process? Assume initial temperature is To = 20C. c) How much work could have been obtained in a reversible process, e.g., by electromagnetic brakes that charge a battery? Compare the possible work to ToSgen.
