A vehicle travels on the highway with the windows closed, in an intense summer in Brazil. The driver is in doubt whether to turn on the car's air conditioning or open the windows. Consider that the cruising speed of the car is equal to 120 km/h, the drag coefficient of the car with the windows closed is equal to 0.40 and 0.48 with the windows open, the air density is equal to 1.225 kg/m³. The car's driving force is equal to 5000N, the height of the car is 1.4m and the width is 1.8m. Knowing that air conditioning increases consumption by approximately 10%, it is worthwhile for the driver to drive with the air conditioning or the windows open (disregard other forces, consider only the drag force, the driving force and the consumption of the driving force generated by the air conditioning on)?
