Answer:
95.3 N
Explanation:
The tension in the cable is found by the equation:
Where is the mass density, and
is velocity.
First we find mass density:
-->
is mass:
and
is length of the cable:
, so:
And the velocity:
the time is and in that time the pulse went down and back along the cable 4 times, if one time down and back is:
2*4.15m=8.3m,
four times this path is:
4*8.3m=33.2m
thus, the velocity is:
And with this data we can now calculate the tension:
The tension is 95.3N
