Wind resistance varies jointly as an object's surface area and velocity and traveling at 40 miles per hour with surface area of 25 square feet experience a wind resistance of zas Newtons. how fast must a car with 80 square feet of surface area travel in order to experience on resistance of 180 newton?
a Velocity = 10 miles per hour c. Velocity = 30 miles per hour b. Velocity = 25 miles per hour d. Velocity = 5 miles per hour

Answer:
C. 2
Step-by-step explanation:
b=k/d
2/3=k/6
k=4
b=4/d
b=4/2
b=2
