Assume that water issuing from the end of a horizontal pipe. 7.5 m above the ground describes a parabolic path. The vertex of the parabolic path . The vertex of the parabolic path is at the end of the pipe. At a position 2.5 m below the line of the pipe . At a position 2.5 m below the line of the pipe , the flow of water has curved outward 3m beyond the vertical line through the end of the pipe. How far beyond this vertical line will the water strike the ground ?

Answer

`3sqrt(3)`
