A 66 g bungee cord has an equilibrium length of 1.20 m. The cord is stretched to a length of 1.80 m, then vibrated at 30 Hz. This produces a standing wave with two antinodes. What is the spring constant of the bungee cord?
Added by Eva C.
Step 1
The tension in a stretched string or cord is given by the formula T = μv^2, where μ is the linear mass density of the string and v is the wave speed. The linear mass density μ is the mass of the string divided by its length. In this case, μ = 66 g / 1.80 m = Show more…

A $75 \mathrm{~g}$ bungee cord has an equilibrium length of $1.2 \mathrm{~m}$. The cord is stretched to a length of $1.8 \mathrm{~m},$ then vibrated at $20 \mathrm{~Hz}$. This produces a standing wave with two antinodes. What is the spring constant of the bungee cord?
A 111.7 g cord has an equilibrium length of 1.44 m. The cord is stretched horizontally to a length of 11.83 m, then vibrated at 48.4 Hz. This produces a standing wave with two antinodes. What is the spring constant of the cord?
