Chapter 17 - 17.11

11. The wave speed v is given by v = τ/µ ,where τ is the tension in the rope and µ is the linear

mass density of the rope. The linear mass density is the mass per unit length of rope: µ = m/L =

(0 . 0600 kg) / (2 . 00 m) = 0 . 0300 kg / m. Thus

v =

500 N

0 . 0300 kg / m =129m / s .
