For examples , find the potential energy of the block at 0.05 m from the mean position

Explanation

To find the potential energy of the block at a distance of 0.05 m from the mean position, we can follow these steps:

### Step 1: Understand the System
We have a mass attached to a spring with spring constant \( k \). The mean position is the equilibrium position where the spring force balances the weight of the mass.

### Step 2: Identify the Displacement
The displacement from the mean position is given as \( x = 0.05 \, \text{m} \).
