Bungee Jumping Problem

  1. Dec 4, 2008 #1
    Bungee jumping- The unstretched length of the cord is 25.0m, the student weighs about 700N, and the balloon you start at is 36.0 m above the surface of the river below. Calculate the required force constant of the cord if the student is to stop safely 4.00m above the river.

    So would I want to use F=kx, then set k=(F/x)...?

    F=700 N
    x=9 m
    k=77.77 N/m

    Is that right?

    Hi Marc! Welcome to PF! :smile:

    Isn't that when acceleration is zero?

    You want the velocity to be zero. :wink:
