You recently drove on the highway and kept a record of every time you passed a car. You found that you did 28 such passes, each time you accelerating from 100 km/h to 120 km/h to complete the pass and then drop down to 100km/h after the pass. Assuming the mass of your vehicle was 2,000 kg, that the energy density of the gasoline you used was about 36000 kJ/L, and that your engine efficiency is about 25%, how much extra fuel did you use just to accelerate for doing those passes? (Report your result in the unit of liters, L). Your Answer: Answer
