Question

What is the equation for:
A bungee cord is stretched between two poles with a force of 393 N. The length of the cord is 36 meters and it has a mass of 5.5 kg. What is the velocity of a wave on this bungee cord? What is the equation for:

A bungee cord is stretched between two poles with a force of 393 N. The length of the cord is 36 meters and it has a mass of 5.5 kg. What is the velocity of a wave on this bungee cord?

Explanation / Answer

The velocity of a wave on this bungee cord is given by
V = sqrt(T/u)
Here T = tension in the cord = 393 N
u = mass per unit length or linear mass density = 5.5/36 = 0.153 kg/m
Hence,
V = sqrt(393/0.153) = 50.7 m/s
