Homework Statement
Scientists want to place a 4400.0 kg satellite in orbit around Mars. They plan to have the satellite orbit at a speed of 2645.0 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
What radius should the satellite move at in its orbit? (Measured from the center of Mars.)
Homework Equations
v = 2∏r/T
The Attempt at a Solution
This question makes no sense. Is there any way to calculate the period of the motion using a different equation? Otherwise, there are two unknowns, irrespective of which equation is used. Even if I attempt to use two different equations that are solved for T and equate them, there is always an unknown such as frequency or acceleration present along with radius.
