The aerodynamic drag on a car depends on the shape of the car. For example, the car shown in Fig. 3 has a drag coefficient of 0.36 with the windows and roof closed. With the windows and roof open, the drag coefficient increases to 045. With the windows and roof open, at what speed is the amount of power needed to overcome aerodynamic drag the same...

Dr. C. #2. (PHYS 121 engineering design exercise) You have seen why cars inherently accelerate quicker in a straight line and have better fuel mileage than an SUV with the same engine; it's because of air drag and the smaller frontal area and better drag coefficient of the car. Now let's think about why cars handle (take turns, change lanes and make other quick maneuvers) better than an SUV. We'l1 simplify our analysis by considering a vehicle of mass M...
