A soft rope that weight 2.0 pounds is stretched by the force of 150 lbf a wave is started down the rope by plucking it. What is the speed of the wave in m/s

Solution

We need to know the length of the rope to find the linear density of the rope. So, let it be 1 m.

$$v = \sqrt {\frac {F}{\mu}} = \sqrt {\frac {F l}{m}} = \sqrt {\frac {150 \cdot 4.448222 \, N(1 \, m)}{2.0 \cdot 0.453592 \, kg}} = 27 \, \frac{m}{s}.$$

Answer: $27 \, \frac{m}{s}$.
