A satellite orbits the earth at a distance of 10,000 miles from the earths’s center. At this distance the force of gravity on the satellite is 111 lbs. what would the force on the satellite be if the distance were 5,000 miles instead?

space probe is launched from Earth headed for deep space. At a distance of 10,000 miles from Earth's center, the gravitational force on it is 929 lb. What is the size of the force when it is at each of the following distances from Earth's center? (a)    20,000 miles lb(b)    30,000 miles lb(c)    100,000 miles

In a geosynchronous orbit, a satellite stays above the same point on Earth because it takes exactly one day to go through one orbit of 2(pi) radians. If the radius of this orbit is 42,100 km, how fast is the satellite traveling around the Earth? pick the one equation and define the relevant knowns and single unknown.

A satellite is in circular polar orbit around Earth at an altitude of 450 km – meaning it passes directly overhead of the North and South Poles. What is the magnitude and direction of the displacement vector when it is directly over the North Pole to when it is at 40° latitude? Earth’s radius is 6,370 km.
