A water hose is used to fill a large cylindrical storage tank of diameter of 1m and height of 2m. The hose shoots the water at 50 degrees above the horizontal from the same level as the base of the tank and is a distance 10m away. For what range of launch speeds will the water enter the tank?

    et launch speeds be u & v for 10m & 11m respectively both at 2m height Case 1: time = 10 / u cos 50 vertical motion, s =ut + 0.5at^2 2 = u sin50 * 10 / u cos 50 - 0.5 * 9.81 * [ 10 / u cos 50 ]^2 2 = 10 tan 50 - 1187 / u^2 1187 / u^2 = 9.9175 u = 10.94 m/s answer Case 2: time = 11 / v cos 50 vertical motion, s =ut + 0.5at^2 2 = v sin50 * 11 / v cos 50 - 0.5 * 9.81 * [ 11 / v cos 50 ]^2 2 = 11 tan 50 - 1436.36 / v^2 1436.36 / v^2 = 11.11 v = 11.37 m/s
