Solve.Wind resistance or atmospheric drag tends to slow down moving objects. Atmospheric drag varies jointly as an object's surface area A and velocity v. If a car traveling at a speed of 40 mph with a surface area of 35 ft2 experiences a drag of 168 N (Newtons), how fast must a car with 49 ft2 of surface area travel in order to experience a drag force of 388.08 N?
A. 63 mph B. 68 mph C. 71 mph D. 66 mph
