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.

Respuesta :

Elastic potential energy is given by formula

[tex]U = \frac{1}{2} kx^2[/tex]

here we know that

[tex]k = 800 N/m[/tex]

[tex]x = 6 m[/tex]

Now using above formula we have

[tex]U = \frac{1}{2}(800)(6^2)[/tex]

[tex]U = 14400 J[/tex]

So elastic potential energy in the chord is 14400 J

Answer:

14400
