Homework Statement A transverse wave on a cord is given by D(x, t) = 0.19sin(2.9x - 35t), where D and x are in m and t is in s. 1) At t = 8.6*10^-2 s, what is the displacement of the point on the cord where x = 0.62 m? 2) At t = 8.6*10^-2 s, what is the velocity of the point on the cord...

Scratch that, I figured it out! Since d = l, I replaced l with d in the equation. d = 0.53sqrt(37l/0.54) ---> d = 0.53sqrt(37d/0.54) d/sqrt(d) = 0.53sqrt(37/0.54) ---> d/sqrt(d) = 4.387 d/sqrt(d) = d^(1/2) ---> sqrt(d) = 4.387 d = (4.387)^2 d = 19.246! Took me a while to get it through my...

vt is equal to the distance, but the trouble I am having is that the distance, d, that i am attempting to find is equal to the length of the string, l. So i must either be using the wrong formula, or some key piece of information is escaping me. This is where I am at right now, using the...

Homework Statement Two children are sending signals along a cord of total mass 0.54 kg tied between tin cans with a tension of 37 N. It takes the vibrations in the string 0.53 s to go from one child to the other. How far apart are the children? Express your answer using two significant...
