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 40 mph with a surface area of 38 ft2 experiences a drag of 228 N (Newtons), how fast must a car with 37 ft2 of surface area travel in order to experience a drag force of 305.25 N?
A. 52 mph
B. 57 mph
C. 55 mph
D. 60 mph
