Homework Help: physics help

Posted by Anonymous on Tuesday, April 27, 2010 at 12:34pm.

A ski gondola is connected to the top of a hill by a steel cable of length 680 m and diameter 1.7 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 15 s for the pulse to return. What is the speed of the pulse? AND What is the tension in the cable? I thought part 1 was t=distance/speed but the answer was not correct. Please help!
