The work required to stretch or compress a spring is given by the formula $ W = \frac{1}{2} k x^2 $, where $W$ is the work done, $k$ is the spring constant, and $x$ is the displacement from the equilibrium position in meters. Given $k = 2500 \, \text{N/m}$ and $x = 4.0 \, \text{cm} = 0.04 \, \text{m}$, the work done is $ W = \frac{1}{2} \times 2500 \, \text{N/m} \times (0.04 \, \text{m})^2 = 2.0 \, \text{J}$.
