The force on a surface due to wind is given by the equation:
F = kv^2 A
where:
F is the force in pounds
k is a constant of proportionality
v is the wind velocity in feet per second
A is the area of the surface in square feet
In this case, we are given that the area of the surface is 32 square feet and the wind velocity is 15 miles per hour. We are also given that k = 0.007486979, which is the value of the constant of proportionality that was determined in a previous problem.
Plugging in these values, we can calculate the force as follows:
F = 0.007486979 * (15 * 15) * 32 = 15.39 pounds
Therefore, the force on a surface of 32 square feet with a velocity of 15 miles per hour is 15.39 pounds.
To round the answer to the nearest tenth of a pound, we would get 15.4 pounds.
