Scientists want to place a 4200 kg satellite in orbit around Mars. They plan to have the satellite orbit a distance equal to 1.7 times the radius of Mars above the surface of the planet.
1) What is the force of attraction between Mars and the satellite?
2) What speed should the satellite have to be in a perfectly circular orbit?
3) Which of the following quantities would change the speed the satellite needs to orbit at?
4) What should the radius of the orbit be (measured from the center of Mars), if we want the satellite to take 8 times longer to complete one full revolution of its orbit?
