Homework Statement
A piano wire with mass 3.25 g and length 84.0 cm is stretched with a tension of 27.0 N. A wave with frequency 100 Hz and amplitude 1.30 mm travels along the wire.
Homework Equations
The only equation that I think applies to this one is P = .5*Sqrt(μ*F)*(omega^2)*A^2...
Thanks, that makes sense. I just had to go through the derivation for x = Acos(ωt + φ), which ended up after a bunch of work showing (k1 + k2) / m = ω2 , which is what he wanted
I'm trying to write a lab report but I cannot figure out how to derive the formulas for my Theories and Derivations section.
Basically, the set-up was this:
Two springs were attached to either ends of a dynamics cart. Each spring was then attached to a bumper at either end of the dynamics...
