Question

A string with a linear mass density of 12.5 g/m is held at a tension of 81.7 N. If the string is plucked, what would be the speed of propagation of the subsequent wave?

Answer 1

Firstly let's change the units for the linear density of the string to kg/m

μ = 12.5/1000 = 0.0125 kg/m

v = √(T/μ) = √(8.7/0.0125) = 26.4 m/s
