Chapter 13, Problem 44P
The Moon and Earth rotate about their common center of mass, which is located about 4700 km from the center of Earth. (This is 1690 km below the sufrace.) (a) Calculate the acceleration due to the Moon’s gravity at that point. (b) Calculate the centripetal accelereation of he center of Earth a sit rotates about that point once each lunar month (bout 27.3 d) and compare it with the acceleration found in part (a). Comment on whether or not they are equal and why they should or should not be.

A space station is constructed in the shape of a wheel 20 m in diameter, with essentially all of its 5.2×105 kg mass at the rim. Once the station is completed, it is set rotating at a rate that requires an object at the rim to have radial acceleration g , thereby simulating Earth's surface gravity. This is accomplished using two small rockets, each with 130 N thrust, that are mounted on the rim of the station. How long will it take to reach the desired spin rate, and how many revolutions will the station make in this time?
What centripetal force does an 77.4 kg passenger experience when seated 10.1 m from the center of a Ferris wheel whose angular speed is 0.500 rad/s?
It has been suggested that rotating cylinders about 14.0 mi long and 3.91 mi in diameter be placed in space and used as colonies. What angular speed must such a cylinder have so that the centripetal acceleration at its surface equals the free-fall acceleration on Earth?
