Answer

$W = x-\frac{x^2}{2L_0}+\frac{L_0^2}{L_0+x}-L_0$

Work Step by Step

We know the following equation for work: $W=\int_0^{x}F(x)dx$ Thus, we find: $W=\int_0^{x}F_0[\frac{L_0-x}{L_0}-\frac{L_0^2}{(L_0+x)^2}]dx$ $W=\int_0^{x}F_0[1-\frac{x}{L_0}-\frac{L_0^2}{(L_0+x)^2}]dx$ $W = x-\frac{x^2}{2L_0}+\frac{L_0^2}{L_0+x}-L_0$
