    Max % Change in Station Angular Speed Due to People Movement

    So instead of using Ekin=1/2mv^2, I will use Ekin=1/2Iw^2? I think I need to do the calculation when r=82.5m for when the people are at outer edge of the cynlindrical satellite and then do another when r=0m for when the people are at the axis. I'm just not sure how I can do this with the...

    Max % Change in Station Angular Speed Due to People Movement

    Homework Statement A cylindrically shaped space station is rotating about the axis of the cylinder to create artificial gravity. The radius of the cylinder is 82.5 m. The moment of inertia of the station without people is 3.00 x 10^9 kg m^2. Suppose 500 people, with an average mass of 70.0 kg...
