A landscape architect is designing a water fountain for a new park. The fountain’s water jet follows a parabolic path. To create a visually appealing effect, the architect wants to design the fountain such that the water jet reaches a maximum height of 4 meters and lands 6 meters away from the nozzle on the same horizontal level. The architect has decided to use a pump that provides a variable water pressure, which affects the horizontal dilation of the parabolic path.
Determine the equation that models the height, $h(x)$, of the water jet as a function of the horizontal distance, $x$, from the nozzle. Further, analyse how changing the water pressure (which effectively dilates the parabola horizontally) would impact the equation and discuss what constraints might be necessary to ensure the water jet still meets the design requirements (maximum height of 4 meters and landing 6 meters away). Justify your reasoning.
