A cylinder with a radius of 15 km is built in space for use as a space station. This cylinder is rotating about its long axis to generate ‘artificial gravity’. When people walk on the inner surface of the spinning cylinder, the normal force between their feet and that surface would provide the needed centripetal force on these people. What angular velocity would generate enough centripetal force so that they feel like they are experiencing the earth’s gravitational acceleration g?
