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?

  • algebra -

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

    now figure power
    power=k*15^3

  • algebra -

    i don't understand
