A 60kg bungee jumper jumps from a bridge. He is tied to a 12m-long bungee cord and falls a total of 31m(adsbygoogle = window.adsbygoogle || []).push({});

a) calculate the spring constant of the bungee cord

b) calculate the maximum acceleration experienced by the jumper

okay I'm stuck on b) I got a0 calculated without any problems at all, it will be 101N/m the problem with b) is that I initially thought.... how would it be possible to have an acceleration of more then 9.8m/s^2 while falling.... it isn't! but I never took into consideration the acceleration while going back up and now whatever I do I alwasy come back to the 9.8m/s^2 answer, I need someon to point me in the right direction so I can get off of this damn idea of 9.8m/s^2
