# What is the value for k if a spring stretches 0.4 m when submitted to an 1800 N force?

## Question:

What is the value for k if a spring stretches 0.4 m when submitted to an 1800 N force?

## Spring Constant:

• The force developed in the spring is proportional to the change in length of the spring. We have the following formula for the spring force.
• {eq}\displaystyle F= k x {/eq} where k is spring constant and x is the change in lenght of the spring.
