The moon orbits the earth with a tangential velocity of 1,022 m/s, and the orbital radius of the moon around the earth is 3.85 x 10 m. The mass of the moon is 7.35 x 1022 kg.
a. What is the orbital period of the moon around the earth? Convert to days.

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 .
