Wind farms are a source of renewable energy found around the world. The power P (in kilowatts) generated by a wind turbine varies directly as the cube of the wind speed v (in meters per second). If a turbine generates 700kW in a 5 m/s wind, how much power does it generate in a 14 m/s wind?
A. 76,832 kw
B. 5,488 kW
C. 15,366 kW
D. 30,733 kW

anonymous · Answer

is it suppose to say, '70,000kw'?

becuase the nubmers don't make sense:

    v    |     P
  12        700kw
   6        (only options are LARGER than 700kw)

the logic doen'st make sense... :(
