The force required to compress a non-standard spring as a function of displacement from equilibrium x is given by the equation F(x) = ax2 - bx, where a = 65 N/m2, b = 18 N/m, and the positive x direction is in the compression direction of the spring.
Part (a)
Write a general equation in terms of the given variables for the work required to compress this spring from equilibrium to any point xp.
