Scientists want to place a 3 x 130 kg satellite in orbit around mars. they plan to have the satellite orbit a distance equal to 1.9 times the radius of mars above the surface of the planet. here is some information that will solve this problem:
mmars = 6.4191 x 1023 kg
rmars = 3.397 x 106 m
g = 6.67428 x 10-11 n-m2/kg2
a-what is the force of attraction between mars and the satellite?
b-what speed should the satellite have to be in a perfectly circular orbit?
c-how much time does it take the satellite to complete one revolution?
d-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?
