A spring with a constant of 76 N/m is extended by 0.9 m. How much energy is stored in the extended spring?

Explanation:

The force constant of the spring, k = 76 N/m

The extension in the spring, x = 0.9 m

We need to find the energy is stored in the extended spring. The energy stored in the spring is given by :

So, 30.78 J of energy is stored in the spring.

it was hot sunny
