One way to provide artificial gravity (i.e., a feeling of weight) on long space voyages is to separate a spacecraft into two parts at the ends of a long cable, and set them rotating about their center of mass. A craft has been separated into two parts with a mass of 82800 kg each, at the ends of a cable with their centers of mass 92 m apart, rotating around the center point of the cable with a period of 186.1 seconds. If the cable is reeled in so that the the centers of the two pieces are now only 69 m apart, what will be the new period?

An asteroid has a mass of m = 2.6 x 106 kg and is approaching Earth. When the asteroid is exactly 3 radii away from the Earth's centre, it's speed relative to the Earth's centre is u = 8.7 x 103 ms-1. The asteroid then falls to the Earth's surface, but remains intact without dissipating any energy as it passes through the Earth's atmosphere. If the rotation of the asteroid and the Earth is ignored, what is the kinetic energy of the asteroid just before it hits the ground?
A uniform rod of mass 0.03 kg and 0.2 m long rotates in a horizontal plane about a fixed vertical axis through its center. Two small bodies, each of mass 0.02 kg are mounted so that they can slide along the rod. They are initially held by clips at positions 0.05 cm on each side of the center and the system is rotating at 15 rev/min. Without otherwise changing the system, the clips are released and the masses slide outward along the rod toward the ends. What is the angular velocity of the system at the instant when the small masses reach the ends of the rod?

If the rotation of the asteroid and the Earth is ignored, what is the kinetic energy of the asteroid just before it hits the ground? The Earth has mass ME = 5.98 x 1024 kg and a radius of 6.38 x 106 m. To find the relevant potential energies, you must use G = 6.67 x 10-11 N m2 kg-2

A space station is constructed in the shape of a hollow ring of mass 4.35 x 104 kg. Members of the crew walk on a deck formed by the inner surface of the outer cylindrical wall of the ring, with radius 110 m. At rest when constructed, the ring is set rotating about its axis so that the people inside experience an effective free-fall acceleration equal to g. (See figure below.) The rotation is achieved by firing two small rockets attached tangentially to opposite points on the rim of the ring. (a) What angular momentum does the space station acquire? |kg · m2/s (b) For what time interval must the rockets be fired if each exerts a thrust of 140 N?
