This is my first time here! Thanks for the help in advance.(adsbygoogle = window.adsbygoogle || []).push({});

The staples inside a stapler are kept in place

by a spring with a relaxed length of 0.115 m.

If the spring constant is 45.0 N/m, how

much elastic potential energy is stored in the

spring when its length is 0.145 m? Answer in

units of J.

I know I have to use F=kx (maybe), but what's confusing me is the potential energy part. How do I fit that into finding the answer?
