DUH! I was trying all these equations! I feel like a fool! So vo=0m/s. Got it.

Well his acceleration would be 9.8 m/s2 right? I'm not sure about velocity... :( Would you use a kinematics equation? SE=1/2kx2 x=22.2-2.58=19.62 So you use the unstretched length instead of the total length! Thanks again!

Am I going about this the right way? When He leaves the balloon: KE=PE .5mv^2=mgh .5(326/9.8)v^2=326(33.6) v^2=658.66 v=25.7 m/sThe 4 is actually supposed to be 2.58. Sorry about that. Equation for stored elastic energy- PEs=(1/2)kx2 The bungee cord develops tension when everything is...

The first equation for that would be KE=1/2mv2 So it would be (1/2)(326/9.8)v2, right? Don't get upset, but how would would you find velocity in this situation? The second one would be mgh, and That is (326)(33.6-4) So his potential would be 294 J? Is that right? The last one would...

Spring Constants and Conservation?? Homework Statement In the dangerous “sport” of bungee-jumping, a daring student jumps from a balloon with a specially designed elastic cord attached to his waist. The unstretched length of the cord is 22.2 m, the student weighs 326 N, and the balloon is...
