Question

A bungee cord stretches 25 meters and has a spring constant of 140 N/m. How much energy is stored in the bungee cord

Answer 1

The energy stored in the bungee cord is 43,750 J.

Step-by-step explanation:

Given;

extension of the bungee cord, x = 25 m

spring constant of the bungee cord, k = 140 N/m

The elastic potential energy stored in the bungee cord is calculated as;

U = ¹/₂kx²

U = ¹/₂(140)(25)²

U = 43,750 J

Therefore, the energy stored in the bungee cord is 43,750 J.
