AP Physics 1: Work and Energy 17: Conservation of Energy: Bungee Jump Problem
Macau Bungy jump - World's Tallest Bungy In this video, it looks like the jumper fell for 5 seconds (1:47 to 1:52) before the cord began to stretch. So I calculated the distance fallen (½ g t2) in 5 seconds to be about 125m. That’s what I used for the relaxed length of the bungee cord. In this video, we can see that the cord looks wavy even when the bungee cord was stretched. That is because there are waves traveling through the cord. We will study waves in the last ~ ¼ of the curriculum.
World's Tallest Bungee Jump HD (233m) Macau 2012 You can see the side view of the jump and the tower in this video.
