## Question:

Suppose that a spring has a natural length of 30 cm, and that 8 J of work is needed to stretch, from a length of 55 cm, to 65 cm. How far beyond its natural length will a force of 32 N keep the spring stretched?

## Spring Constant:

We know that a spring is an object that has a stored elastic energy. We must take note that the capability of springs to store elastic energy is based on its spring constant, which has a unit of the amount of force per unit length.
