A landscape architect is designing a park and wants to incorporate curves modeled by polynomial functions. The architect is particularly interested in using a cubic polynomial to create a smooth transition between two flat sections of the park. The cubic polynomial, $P(x)$, will be used to model the height of the terrain along a section of the park, where $x$ represents the horizontal distance in meters.
b. The architect also wants the maximum height of the terrain to be 1 meter. Determine the value of $a$ in $P(x) = ax^2(x-4)$ such that the maximum height of the terrain is 1 meter. Show your working.
