Finding tension given speed of a pulse, length, radius, and time

  1. Nov 6, 2009 #1
    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 have no idea.



    3. The attempt at a solution
    I don't even know where to start. I don't even see how you can calculate tension with the information. Any help is appreciated. Thank you!
