a satellite traveling in a circular orbit 2000 kilometers above the earth completes one orbit every 3 hours. assume the earth is a sphere and its radius is 6400 kilometers. find the angular velocity of the satellite

Answer 1

radius of circle is 2000+6400 = 8400 km.

But that does not matter when all we want is the angular velocity.

ω = (2πrad)/(3hr) = (2π/3) rad/hr
