# The Spring Potential Energy of a Trampoline

## Understanding Spring Potential Energy Calculation:

**Spring Potential Energy Calculation Formula:**

The spring potential energy 'U' of the trampoline can be calculated using Hooke's Law for elastic potential energy.

The formula to find the spring potential energy is: **U = Â½ kxÂ²**

## Calculating the Spring Potential Energy:

Given parameters:

Mass of the bowling ball (m) = 20kg

Spring constant (k) = 2000 N/m

Displacement from equilibrium (x) = 0.5 m

Using the formula:

U = Â½ (2000 N/m)(0.5 m)Â²

U = Â½ (2000)(0.25)

U = Â½ (500)

U = 250 Joules

Therefore, the spring potential energy of the trampoline with these given parameters is 250 Joules.
