A ski gondola is connected to the top of a hill by a steel cable of length 620 m and diameter 1.5cm. 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 16 s for the pulse to return.
(a) What is the speed of the pulse?
(b) What is the tension in the cable? |
