Find the force applied to you by the rubber bands?

  1. Nov 10, 2008 #1
    1. The problem statement, all variables and given/known data

    A giant rubber band is going to launch you straight upwards. Upon launch your acceleration is 15 m/s^2 upwards. If your mass is 70 kg, find the force applied to you by the rubber bands.

    This is a copy word from word of the problem. Please be specific. I have a physics test tomorrow.

    Thanks!!


    2. Relevant equations



    3. The attempt at a solution

    a = 15 m/s^2
    M = 70 kg
    F = ?

    F = ma
    F = (70 kg)(15 m/s^2) = 1050 N

    That's the net force on you during the acceleration, not the force from the rubber band.

    Draw a free body diagram of you. What forces are acting? Which way do they act?

    I do not know. I am looking but can't figure it out.
