What is the wave speed?

  • #1
The linear density of a string is 5.520×10-3 kg/m. A transverse wave on the string is described by the equation

y=(0.033 m)sin(2.50 m-1x +125.7 s-1 * t).

1.) What is the wave speed?




2.) What is the tension in the string???


I've already calculated the wave speed but I don't know how to do the tension in string!

HELP PLS!

wave speed (v) = w/k

y= Asin(kx-wt)

w = 125.7
k=2.5

v = 125.7/2.5 = 50.38 m/s (wave speed)


But i do not know how to calculate the tension!!! HELP PLEASEE!!
