Question

A bungee cord with a spring constant of 800 StartFraction N over m EndFraction stretches 6 meters at its greatest displacement. How much elastic potential energy does the bungee cord have? The bungee cord has J of elastic potential energy.

Answer 1

14,400J

Step-by-step explanation:

Answer 2

P.E = 14,400J or 14.4kJ

Step-by-step explanation:

Hello,

This question requires us to calculate the elastic potential energy of a cord. To do this, we should get our data first from the question and then proceed on how to approach the question.

Data;

Spring constant (k) = 800Nm²

Displacement (x) = 6m

Elastic potential energy (P.E) = ½kx²

P.E = ½kx²

k = force or spring constant

x = displacement

P.E = ½ × 800 × 6²

P.E = ½ × 28800

P.E = 14,400J

P.E = 14.4kJ

The potential energy is 14,400J or 14.4kJ

Therefore, the bungee cord has a potential energy of 14.4kJ
