1. The pro blem statement, all variables and given/known data
the question:
9.0 × 10^3 kg satellite orbits the Earth at the distance of 2.56 × 10^7 m from Earth’s surface. What is its period?
They give me a multiple choice, but let's figure this out without it.
okay so my variables known are the mass of the satelite:
"MSat"- 9.0*10^3
d/r= 2.56 × 10^7 m
mearth: 5.9742 × 10^24 kilograms
G= 6.67*10^-11
Kepler's Law (?)
T^2= 2*pi*r(^3/2)/G*Mp
So for some reason I bet that equation is NOT correct. I've been searching all over google and through my notes and its all i can come up with. I'm not sure if I use the mass of the satelite or the mass of Earth in the equation. I don't understand why they would even give me the mass of the satelite if I am not supposed to use it though
so I put into my calculator: T=squrt: 2*(3.14)^2* 2.56 × 10^7 m (or is it the radius of earth+the distance given(?) / (6.67*10^-11)* 5.9742 × 10^24
or do i use the mass of satelite here?
