## Question:

A block weighs 15 N and is suspended from a spring that is attached to the ceiling. The spring stretches by 0.075 m from its unstrained length. By how much does the spring stretch when a 36-N block is suspended from it?

## Hooke's Law:

When an object is allowed to suspend freely at the end of spring in vertical position with other end fixed, it causes elongation of the spring such that the weight of the object is proportional to the elongation of the spring, which is based on Hooke's law.
