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, it will simply accelerate downward with the gravitational acceleration, 10 m/s2. With what speed will it be going when it gets to the ground in m/s? (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. ).
