P=FV

## The Attempt at a Solution

To calculate the mass of wind swept by turbine in a second, I take 2000m

^{2}×10ms

^{-1}×1.3kgm

^{-3}.Then, to calculate the force I multiply the answer with 10ms

^{-1}. Since they want the power and the yield is 50%. I multiply the answer again with 10ms

^{-1}and divide it by two. This gives me C as the answer. However, the answer is B. So where did I go wrong?
