Elastic Potential Energy:

U is energy (in J)k is spring constant (in N/m)Δx is displacement from equilibrium (in m)Explanation:

Step 1: Define

k  = 7.50 N/m

Δx = 0.40 m

Step 2: Find Potential Energy

Substitute in variables [Elastic Potential Energy]:                                        Evaluate exponents:                                                                                      Multiply:                                                                                                           Multiply:
