The force required to deform a spring is proportional to the extension of the spring. The current elongation of the spring is $2\mathrm{cm}$ and the force required to reach this elongation is $3\mathrm{N}$. Evaluate the work required to stretch the spring from the current elongation (i.e. $2\mathrm{cm}$) by additional $10\mathrm{cm}$.
