Thought Experiment (Jumping of a building)

  1. Nov 6, 2008 #1
    1. This was just a quick question that I was thinking about.
    If you jump of a really tall building, let's say 100-story building and you fall most likely you won't live to tell the tale.
    But let's say you jumped with a cardboard (or any object) and a couple feet before you hit the ground pushed of the cardboard (like a skateboarder) and jumped and landed on the floor.
    Would you survive because since you jumped you cancel the downward force.

    2. None ... I just thought about it.

    3. I pressumed that by jumping you stop the speed you are going down with and after you jump the downward force starts again. But since you are close to the ground your acceleration isn't large enough to do any damage.

    2. Relevant equations

    3. The attempt at a solution

    How high can you jump?

    At the bottom of your 100 story fall your m*g*h is m*v2/2

    You think you have 100 stories of m*g*h packed in your legs?
