I don't have k or m, and after reading these suggestions, I'm still at a loss as to how to calculate k. I tried making graphs and finding the slope, but it's still dependent on m(which does not come with the problem). Without either k or m, I can't progress. I have finished part a already, the...

For part A, I found the midpoint between 10m and the initial height. I'm not sure how I can calculate k with just the length of the spring and its displacement.

Ok, here is a physics problem that I cannot figure out for the life of me. I feel as though I can't solve it without knowing either the mass of the bungee jumper or the spring constant for the cord. Is there a way to get it somehow? Perhaps an important number is missing? I would appreciate any...
