Suppose that the car in the previous problem has a fuel efficiency of 24 mpg. How much energy is released in burning a gallon of gasoline (assuming that all of it is octane)? Based on this calculation and the work required to move the car those 24 miles, what percentage of the energy released in the combustion is wasted (doesn’t directly contribute to the work of moving the car)? How do the assumptions you make in carrying out these calculations affect the value you obtain?
