A ski gondola is connected to the top of a hill by a steel cable of length 620 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 14 s for the pulse to travel the length of the cable and then return.
(a) What is the speed of the pulse?
I got 88.57 m/s but cannot get part b
(b) What is the tension in the cable?
