Answer:
T = 6.0 N
Explanation:
given,
mass of the cord = 0.46 Kg
length of the supports = 7.2 m
time taken to travel = 0.74 s
tension in the chord = ?
using formula for tension calculation
[tex]T = \dfrac{v^2.m}{l}[/tex]
[tex]v = \dfrac{l}{s}[/tex]
[tex]v = \dfrac{7.2}{0.74}[/tex]
v = 9.73 m/s
now, calculation of tension
[tex]T = \dfrac{9.73^2\times 0.46}{7.2}[/tex]
T = 6.0 N
The tension in the cord is equal to 6.0 N.
