Homework Statement

A force of 5.00 N compresses a spring 5.00 cm. What is the elastic potential energy stored in the compressed spring?

Homework Equations

Ep=1/2kx²

The Attempt at a Solution

Epelastic needs to calculated. I really do not know how to get there. K=f/x
k=5N/ 0.05m
100 N/m
the answer is actually 0.125 J
