Bungee Definition and 148 Threads

we've been studying te physics involved in bungee jumping. We went to a bungee site, and recorded data, such as length of rope, weight of jumper, distance to fall, etc. With the data we collected, I've been able to determine spring constant, equilibrium point, force exerted etc. But I've...

Homework Statement Consider a bungee cord of unstretched length L0 = 43 m. When the cord is stretched to L > L0 it behaves like a spring and its tension follows the Hooke’s law T = k(L − L0). But unlike a spring, the cord folds instead of becoming compressed when the distance between its...

1. there is such a reverse bungee machine called the G-max Reverse Bungee in New Zealand and Singapore. Basically it works by attaching a car to two stretched giant rubber bands, then releasing them from the ground, so that it rockets up (to 60m), quite like reversed bungee jumping. it claims to...
