An object with mass M is sliding along a horizontal, frictionless surface with a velocity of V. It then slides up a hill that is 15 degrees above the horizontal. The object travels a distance D parallel to the surface of the hill before coming to rest.
If the hill does have friction, what is the work down by friction. Give your answer in terms of M, V, D, g, and Constants.

Explanation:
P = bS^3 is the equation we can get from the problem.
The b is the blowing wind's constant of variation. S is the speed of the wind.
Plug in 12 for the speed and 500 for the constant of verition.
P=500(12)^3
P = 864,000
The power generated will be a lot higher with just a little bit more windspeed!
