3.) Automotive engineers work very hard to improve the value of the drag coefficient for cars.  Suppose you have a  car with a mass of 3000. kg and an effective surface area of 4.00 m^2. The engine can generate a maximum force of 28,000. N.   Let the coefficient of kinetic friction be 0.200, and the coefficient of static friction be 0.400.  Air has a density of 1.21 kg/m^3.  (back on earth) (3a) Draw a free-body diagram for your car, including both drag and friction, when the car is moving at its maximum velocity. (3b) If the maximum value of your car's velocity is 150.0 m/s, then what is the drag coefficient for the car? (3c) Suppose your engineers change the drag coefficient to 0.300 - what would be your maximum velocity then with the same force from your engine.
