Suppose a car manufacturer tested its cars for front-end collisions by hauling them up on a crane and dropping them from a certain height. Find the speed just before a car hits the ground, after falling from rest a vertical distance H. ...Considering it doesn't have sqrt2gH, what's the answer. Or is that the answer?

    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...
