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