1. If the INternational space station has an orbital velocity of 9,000 m/s. find the time (in minutes) it takes to make one complete orbit.
Relevant equations
F = mv2/ R = m4[pi]2R / T2
The attempt at a solution
Is this the way to solve for T?
Do I use Earth mass and Earth R b/c that all the question says?
2. A martian day is 1.03 Earth days. At what altitude above Mars should a communications satelite be placed such that it always stay over the same spot above the surface of Mars (answer in units of miles. 1000m = 0.62 miles
Relevant equations
F = ma = m4[pi]2R / T2
a= GM/R2
The attempt at a solution
I know how to solve the problem but what kinda threw me off are the martian days given...
Is T 354.36 days that is 365/1.03
If it is, can i find "a" after the "m" cancel, than solve for R which is (mar's radius + Mars altitude)
3. find the lagrange Point between the sun and Jupiter. In between what two planets will you find this point?
Jupiter:
mass: 1.9x1027 kg
Sun:
mass: 1.99x1030
distance betwwen sun and Jupiter: 778x106 km
Relevant equations
Im really not sure what is lagrange point equation, is it... GMsunmjupiter/ r
r is the distance of Jupiter- sun ?
