Homework Help: Question about skylab speed

  1. Jun 25, 2008 #1
    1. The problem statement, all variables and given/known data

    The attached videoclip shows footage from Skylab, launched in 1973, used during 1973-74, and in orbit until 1979. During the final seconds of the clip, you can see three astronauts exercising. One of them is running around the station. Estimate the speed that he should maintain, in order to feel as if he were running on earth................explain your reasoning and calculations

    2. Relevant equations

    3. The attempt at a solution

    idk, I'm really looking for how to set the problem up more than estimates. I tried this...really no idea if its right or not.

    centrifugal acceleration = v^2 / r

    = g (to feel like you are on earth)

    So v = sqrt (gr)

    and estimated radisu to be about 3m

    That looks right to me. The only thing wrong is your wording. It is centripetal acceleration not centrifugal.
