The force, F, exerted by the wind on a plane surface varies jointly with the square of the velocity, v, of the wind and with the area, , of the plane surface. If the area of the surface is 27 square feet and the wind velocity is 12 miles per hour, the resulting force is 18 pounds. Find the force on a surface of 32 square feet with a velocity of 15 miles per hour. Round the answer to the nearest tenth of a pound. 26.7 pounds 31.6 pounds 33.3 pounds 28.1 pounds
