A ski gondola is connected to the top of a hill by a steelcable of length 620m and diameter 1.5cm. As teh gondola comes tothe end of its run, it bumps into the terminal and sends a wavepulse along the cable. It is observed that it took 16 seconds forthe pulse to return. a) What is the speed of the pulse? b)What isthe tension in the cable?
I believe to find the speed of the pulse all I ahve to do is V=distancetravelled timetake so it would equal 77.5 m/s
To find tension i would use
After manipulating it I get
i know V=77.5 and L = 620 but i dont know how to find m.Please help! I dont even know if I did the rest of the problemright please help as soon as possible. Thanks
