Part B $-$ Hooke's Law

In this section, we'll examine what practical uses springs may have in a static system and determine the

spring constant, $k,$ experimentally. To begin, remove the weight $F_c$ and hang one end of the spring in

your kit from the string. Then, hang the weight $F_c$ from the other end of the spring.

What happened to the geometry of the strings when the spring was introduced? How does it

compare to Part A$?$ Explain.

Draw a free$-$body diagram of the spring to help explain what you saw in $(1).$ Hint: This is a great

application of Newton's third law.

Knowing the force applied, measure the stretch of the spring and use your measurements to

calculate the spring constant $k$ in $\frac{N}{m}$ using Hooke's law.
