Answer

The spring constant of the spring is .

Explanation

## Step 1:The elastic potential energy stored in a spring can be calculated using the formula:### where:- is the elastic potential energy,- is the spring constant,- is the displacement of the spring from its equilibrium position.## Step 2:In this problem, the elastic potential energy is given as , and the displacement is given as . Convert the displacement to meters:### ## Step 3:Rearrange the formula to solve for the spring constant :### ## Step 4:Substitute the given values into the rearranged formula:### \(k = \frac{2 \cdot 4.0 \, \text{J}}{(0.08 \, \text{m})^2}\)## Step 5:Calculate the spring constant :###
