a little wind spinner intended to be purely decorative, but it could be used to capture energy from the wind. At a wind speed of 5 m/s, how much energy do you estimate we could capture with this spinner? For reference, the wooden post that supports the wind spinner is a common wood 4 x 4, whose sides are actually 3-1/2" x 3-1/2". Show all your computations. State any assumptions you are making.
