Answer :
Explanation:
The given data is as follows.
Distance (s) = 20 m
time (t) = 0.775 s
Also, it is given that mass per 1 meter length (m) = 0.300 kg
Formula to calculate the velocity is as follows.
Velocity (v) = [tex]\frac{s}{t}[/tex]
Putting the given values into the above formula as follows.
v = [tex]\frac{s}{t}[/tex]
= [tex]\frac{20 m}{0.775 s}[/tex]
= 25.80 m/s
We know that,
v = [tex]\sqrt{\frac{T}{m}}[/tex]
Taking square on both the sides, the formula will become as follows.
T = [tex]mv^{2}[/tex]
= [tex]0.3 kg \times 25.80[/tex]
= 199.692 N
Therefore, we can conclude that tension in the given tightrope is equal to 199.692 N .
