(II) A four-cylinder gasoline engine has an efficiency of 0.22 and delivers 180 J of work per cycle per cylinder. If the engine runs at 25 cycles per second (1500 rpm), determine (a) the work done per second, and (b) the total heat input per second from the gasoline. (c) If the energy content of gasoline is 120 MJ per gallon, how far can the car go on one gallon (or on one liter), assuming 1500 rpm in high gear corresponds to a speed of 80 km/h?
