Question

A bungee cord with a spring constant of 800 stretches 6 meters at its greatest displacement. How much elastic potential energy does the bungee cord have? The bungee cord has 9600 ⇒ 14,400 J of elastic potential energy.

Answer 1

Elastic potential energy is given by formula

$U = \frac{1}{2} kx^2$

here we know that

$k = 800 N/m$

$x = 6 m$

Now using above formula we have

$U = \frac{1}{2}(800)(6^2)$

$U = 14400 J$

So elastic potential energy in the chord is 14400 J
