Waves, Bungee Jumping, Linear Density Definition

Click For Summary
SUMMARY

The discussion centers on the calculation of linear density (μ) in the context of wave mechanics related to bungee jumping. A participant asserts that the correct linear density should be 89.9 N/m, derived from the formula μ = mass/length, specifically μ = 75 x 10-3 kg / 1.8 m. This correction addresses an error in the book's calculations, emphasizing the importance of accurate measurements in physics problems.

Please look a picture.
I think the book made a mistake.
The answer should be 89.9N/m.
Why? Because they calculated the linear density μ wrongly. They should have done $$\frac{75*10^{-3}kg}{1.8m}$$

I'm pretty sure that you are correct !
