A water hose is used to fill a large cylindrical tank of diameter D and height 2D. The hose shoots at 45 degrees above the horizontal from the same level as the base of the tank and a distance 6D from the tank. For what range of launch speeds will the water enter the tank? Give your answer in terms of D and g.
