Homework Help: Bungee jumping

  1. Nov 24, 2007 #1
    1. The problem statement, all variables and given/known data
    A 75 g bungee cord has an equilibrium length of 1.20 m. The cord is stretched to a length of 1.80 m, then vibrated at 20 Hz. This produces a standing wave with two antinodes.

    2. Relevant equations
    I really am not sure how to approach this using an equation, tried to use

    w = sqrt (k/m)

    3. The attempt at a solution

    using the above equation I got a value of

    1184 N/m for 'k', which is incorrect
