Homework Statement
A wire with mass 35.0 is stretched so that its ends are tied down at points a distance 83.0 apart. The wire vibrates in its fundamental mode with frequency 64.0 and with an amplitude at the antinodes of 0.270 .
it asks for: Tension
Speed of propagation
maxmimum transverse velocity and
maximum acceleration
Homework Equations
Wave equation Asin(kx-wt)
I figured I was suppose to put the equation into this form first, however I was really unsure because I have never done a problem like this before.
The Attempt at a Solution
.270cmSin(7.57x-402.12t)
.270 is given
7.57 i took 2pi/.83 : here I am assuming .83m (83 cm given) is the wavelength, as I did not know what else it could be.
402.12 i have from frequency * 2pi.
I am not sure at all if this is a step in the right direction, any help is really appreciated :)
