4. A satellite made up of non-reflective material and the earth attract each other with a force of "F" while the satellite is on the launch pad. The satellite is launched and experiences the forces shown below at various distances above earth's center (r=radius of Earth).

a. describe the relationship between force and distance.

b. Predict the force on the satellite when it is 3r above the Earth's center. Explain.

c. Create a force vs. distance graph.
