1. The problem statement, all variables and given/known data A satellite moves in a circular orbit around the Earth at a speed of 5.1km/s. Determine the satellite's altitude above the suface of the Earth. Assume the Earth is a homogenous sphere of radius Rearth= 6370km, and mass Mearth=5.98x10^24 kg. You will need G=6.67259x10^(-11) Nm^2/kg^2. Answer in units of km 2. Relevant equations v^2=(G*Mass of earth)/(radius) 3. The attempt at a solution (5100 km/s)^2 = (6.67259x10^(-11))(5.98x10^(24))/r 26010000r=3.990190282e14 r= 15340985.32 - 6370000= 8970985.321m = 8970.985321km i think its wrong, but i dont know where i made the mistake..
