Homework Statement
Given data: A moon of Mars orbits with a period of 459 minutes. The radius of the moon's orbit is 9.4x10^6 m. What is the mass of mars?
Homework Equations
The Attempt at a Solution
The only relevant equation I could find was Fmars on moon= (G*m1*m2)/(r2)
I have the radius, but to solve I would need the mass of the moon and the gravitational force. Could I use F=mv2/r ? Or how about v= [tex]\sqrt{}GM/r[/tex] ?
