Lego got bored of bows, so he went to buy a sling. We approximate it as a spring with constant
stiffness and a zero rest length. Lego can stretch the sling with force F = 31.4 N, and he wants it
to store as much energy as possible while it is stretched. There were two slings at the shop, with
stiffnesses k1 = 159 N/m and k2 = 265 N/m. What will be the difference between the potential
energies of those slings stretched with force F?
