Aski gondola is connected to the top of a hill by a steel cable oflength 620 m and diameter 1.5 cm. as thegondola comes to the end of its run, it bumps into the terminal andsends a wave pulse along the cable. it is observed that it took14 s for the pulse to travel the length ofthe cable and then return.
(a) what is the speed of the pulse?
m/s
(b) what is the tension in the cable?
n
