Question:

A Spring ({eq}k=790 \ N/m {/eq}) has a length of {eq}48 \ cm {/eq} when zero net force is applied to it.

What will its length be when {eq}230 \ N {/eq} of force is applied to stretch it?

Hooke's Law:

The applied force of an ideal sping is the product of the spring constant and the displacement of the spring from its unstrained length. The restoring force is the negative of the applied force, which is a reaction force based on Newton's third law.
