1) Wind resistance tends to slow down moving objects. Wind resistance
varies jointly as an object’s surface area A and velocity v. If a car traveling at a speed of 40 mgℎ with a surface area of 37.8 ft2 experiences a drag of 222 N (Newtons), how fast must a car with 51 ft2 of surface area travel in order to experience a drag force of 430 N?
(A) 25.8 mph (B) 46.5 mph (C) 57.4 mph (D) 62.8 mph (
E) none of the above
