The passenger liners Carnival Destiny and Grand Princess have a mass of
about 1.0 x 108 kg each. How far apart
must these two ships be to exert a
gravitational attraction of 1.0 x 103 N
on each other?

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
