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 33 ft2 experiences a drag of 184.8 N (Newtons), how fast must a car with 38 ft2 of surface area travel in order to experience a drag force of 218.12 N?

A. 38 mph
B. 43 mph
C. 41 mph
D. 46 mph
