Scientists want to place a 3800 kg satellite in orbit around

Mars. They plan to have the satellite orbit at a speed of 2467 m/s

in a perfectly circular orbit. Here is some information that may

help solve this problem:

mmars = 6.4191 x 1023 kg

rmars = 3.397 x 106 m

G = 6.67428 x 10-11 N-m2/kg2

1. What radius should the satellite move at in its orbit?

(Measured frrom the center of Mars.)

2. What is the force of attraction between Mars and the

satellite?

3. What is the acceleration of the satellite in orbit?

4. What should the speed of the orbit be, if we want the

satellite to take 8 times longer to complete one full revolution of

its orbit?
