Answer to Problem 12P
The speed of the wind is:
Explanation of Solution
Given information:
The wind pressure on a plane varies jointly as the surface area and the square of the speed of the wind.
What is the speed of the wind when the pressure on a
Formula used:
For varies directly and inversely:
Calculation:
Consider that What is the speed of the wind when the pressure on a
Recall that varies directly and inversely:
The values are:
Therefore, the value of
So simplified further the value of
Now to find the value of
The values are:
Hence, when:
So,
Thus, the speed of the wind is:
