1. Imagine a 4820 kg satellite in a geosynchronous orbit. If an 85.0 kg piece of space junk floats by at a distance of 3.50 m, what force will the space junk feel?
2. With what acceleration will the space junk move toward the satellite?
3. With what acceleration will the satellite move (if any)?
4. (harder) Using the above information and what you know about kinematics, how far will the satellite have moved when it encounters the space junk, assuming they meet, each moving with the accelerations you solved for in #10, 11?
The moon has a mass of 7.35x1022 kg and is a lot farther away than is shown in textbooks. The mass of the earth is 5.97 x 1024 kg. The moon's mean orbit distance (center-to-center) is around the earth is 3.84x108 m. With all this information determine:
5. The gravitational force on the moon by the earth.
6. The gravitational force on the earth by the moon.
7. The centripetal acceleration of the moon around the earth, realizing that the gravitational force is also centripetal force.
The speed of travel of the moon around the earth, using the formula for the speed of a moving object in a circular path.
