    Conservation of angular momentum of space station

    [SOLVED] Conservation of angular momentum A space station shaped like a giant wheel has a radius of 1.00x10E2 m and a moment of inertia of 5.00x10E8 kgm2. A crew live on the rim and the staion is rotaing so that the crew experiences an apparent acceleration of 1g (1x9.81m/s2). When 120 people...
