Answer:
The period is [tex]T = 13.53 \ sec[/tex]
Explanation:
From the question we are told that
The length of the cable is [tex]L = 45.5 \ m[/tex]
Let take acceleration due to gravity as [tex]g = 9.8 \ m/s^2[/tex]
Now the period of the oscillation is mathematically represented as
[tex]T = 2 \pi \sqrt{\frac{L}{g} }[/tex]
substituting values
[tex]T = 2 * 3.142 \sqrt{\frac{45.5}{9.8} }[/tex]
[tex]T = 13.53 \ sec[/tex]
