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!
