A car starts from rest and accelerates along a straight highway. The car’s engine produces a constant force of 7000 N that drives it forward. The driver finds that his acceleration decreases the faster he goes and that his speed eventually maxes out. What is the maximum speed the car reaches? Ignore friction between the tires and the road. The density of air is 1.2 kg/m3, the drag coefficient of the car is 0.5, and its cross-sectional area is 4 m2
