How should i go about finding the desired velocity for a satellite to orbit mars in a given time.

Question

anonymous · Answer

time=115646.459s
mmars = 6.4191 x 10^23 kg
rmars = 3.397 x 10^6 m
G = 6.67428 x 10^-11 N-m2/kg2

anonymous · Answer

at a velocity of 2650 m/s:
radius of motion (from center of planet) = 6096890m
force of attraction = 4149
acceleration = 1.153

goformit100 · Answer

you can do so by knowing it's RPM.

anonymous · Answer

then i need to know the radius, and the radius is a function of the gravitational attraction witch is also a fucntion of acceleration which is a function of velocity, ahh!

anonymous · Answer

$$r=(\frac{ mGt }{ 2\pi })^{2/3},v=\frac{\sqrt( mG )}{ \sqrt(r) }$$

here is the solution in case anyone is having the same problem
