Answer:
15.13 m/s
Explanation:
The wave speed of the stretched rope can be calculated using the following formula
[tex]v = \sqrt{\frac{F_T}{\mu}}[/tex]
where [tex]F_T = 44N[/tex] is the tension on the rope and [tex]\mu = m/L = 0.5 / 2.6 = 0.1923 kg/m[/tex] is the density of the rope per unit length
[tex]v = \sqrt{\frac{44}{0.1923}} = \sqrt{228.8} = 15.13 m/s[/tex]
