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 5m.s wind, how much power does it generate in a 14m/s wind?

power=k*speed^3
k=power/speed^3=700kw/125

now figure power
power=k*15^3
