For next year's Physics Open House the Department is planning to set up a bungee jump from
the top of the physics building. Assume that one end of an elastic band will be firmly attached
to the top of the building and the other to the waist of a courageous participant. The
participant will step off the edge of the building to be slowed and brought back up by the
elastic band before hitting the ground (we hope). Estimate the length and spring constant of
the elastic you would recommend using.
This is presented as a Fermi problem so I only need rough approximations, however, I think I am supposed to account for damping effects and I don't really know where to start
