Hawks and gannets soar above the ground and, when they spot prey, they fold their wings and essentially drop like a stone. They

have evolved a highly aerodynamic shape that lets gravity build up their speed without having to make the effort of trying to fly at a high speed (See the figure of a diving hawk below. The technical term for this maneuver is "stooping".) For this problem, you may approximate the strength of the gravitational field as g = 10 N/kg.A. If a hawk is slowly soaring at a height of about 150 meters and spots a vole on the ground, folds its wings and begins its dive, with what speed will it be going when it gets to the ground? It's flight isn't powered: it just falls with an acceleration of ~10 m/s2. (Of course, it has to turn a bit above the ground in order not to crash. We will ignore this part of its flight path.)
