Solve the problem.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 30 mph with a surface area of 35 ft2 experiences a drag of 115.5 N (Newtons), how fast must a car with 40 ft2 of surface area travel in order to experience a drag force of 308 N?
A. 70 mph B. 75 mph C. 67 mph D. 72 mph
