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 30 mph with a surface area of 37 ft2 experiences a drag of 166.5 N (Newtons), how fast must a car with 44 ft2 of surface area travel in order to experience a drag force of 495 N?
A. 80 mph
B. 75 mph
C. 77 mph
D. 72 mph
