A space station in the shape of a 100 m-diameter (50m radius) wheel is spinning so as to impart a linear tangential speed of 22.1 m/s to a point on its outmost wall, thereby providing an artificial gravity of 1g. What should be the tangential speed to increase the artificial gravity to 2 g? a) 44.2 m/s b) 31.3 m/s c) 88.4 m/s d) 27.8 m/s e) 177 m/s Take the Earth and Moon to be a uniform spheres of radius of 6×10^6m and 2×10^6m respectively, and mass 6×10^24kg and 6×10^22kg respectively. The Earth rotates about its axis once per day, and the Moon rotates about its axis once per 30 days. What is the ratio of the angular momentum of the Earth and that of the Moon? (Ratio = L(Earth)/L(Moon)). a) 30 b) 2,700 c) 900 d) 300 e) 27,000
