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 500kw in a 10m/s wind, how much power does it generate in a 12m/s wind? .

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?
