Wind speed varies in the first twenty meters above the ground. For a particular day, let compute the wind speed above the ground. What is the wind speed above the ground

7.61 meters per second

Step-by-step explanation:

The speed of the wind at x meter i.e. above the ground should be

f(x) = 1.5 ln x  + 5.2

Now to determine the wind speed at 5 meters above the ground substitute

i.e.

x = 5 for the above function

= 1.5 ln (5)  + 5.2

= 7.61

So the speed of the wind above the ground is 7.61 meters per second

And the same is to be considered

step-by-step explanation:

i need to answer questions so i dont know but i think its the first one because it goes up but a consent rate

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
