Scientists want to place a 2700.0 kg satellite in orbit around Mars. They plan to have the satellite orbit at a speed of 2554.0 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 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?
