Answer:
P.E = 14,400J or 14.4kJ
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
