1. The problem statement, all variables and given/known data
A ski gondola is connected to the top of a hill by a steel cable of length 580 m and diameter 1.5 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 19 s for the pulse to travel the length of the cable and then return.
(a) What is the speed of the pulse?
61.05263158 m/s
(b) What is the tension in the cable?
? N
2. Relevant equations
I would assume you would sum the forces, but I don't know what to put together to reach a tension.
3. The attempt at a solution
I do not know where to begin.
Help is greatly appreciated! Thank you!
