## Question:

A coiled spring in a waist-trimming exercise requires a force of 54 N to compress it by 0.20 m. Find the force constant of the spring.

## Hooke's Law:

Hooke's law states that the force needed to compress or extend a spring is a linear function of the change in length or stretch distance of the spring and the spring constant. The formula for Hooke's law is shown below.

$$F = k\Delta x$$

Where:

• {eq}F {/eq} is the force.
• {eq}k {/eq} is the spring constant.
• {eq}\Delta x {/eq} is the change in the spring's length.
