A 24m nylon rope has a tension of 1.3x104N. The total mass of the rope is 2.7kg. If a wave pulse starts on one end, how long does it take to reach the other end.
I get 0.07s
[tex]v=\sqrt{\frac{T}{\mu}}[/tex]
[tex]t=d/v=d\sqrt{\frac{\mu}{T}}[/tex]
[tex]\mu=\frac{m}{l}=\frac{2.7kg}{24m}[/tex]
[tex]t=d/v=d\sqrt{\frac{m}{Tl}}=0.07s[/tex]
Book has 1.6s
