Physics
A ski gondola is connected to the top of a hill by a steel cable of length 600 m and diameter 1.2 cm . As the gondola comes to the end of its run, it bumps into the terminal and sends a wave pulse along the cable. It is observed that it took 18 s for the pulse to return. Part A What is the speed of the pulse?

Ответ:
v = 66.7 m/s
Explanation:
Given that,
The length of steel cable, L = 600 m
Diameter = 1.2 cm
It is observed that it took 18 s for the pulse to return.
The time taken to cover 600 m will be :
t = T/2
t = 9 s
Let v be the of the pulse. We know that,
So, the speed of the pulse is equal to 66.7 m/s.
Ответ:
I think that the answer is 1500 Kg
