A 2150 kg satellite is in a circular orbit 780 km (780 x 103 m) above the surface of the earth. You can find the details of the earth’s mass and radius on the inside front page of your textbook.
a.) What is the gravitational force on the satellite due to the earth?
b.) What is the speed of the satellite in its orbit?
c.) What is the period of the orbit?
d.) If an identical satellite were launched from Earth to go outside the solar system, what would its escape speed have to be?
