se the exact values you enter to make later calculations. Satellites feel the gravitational pull of the Earth. They remain in orbit because of their velocity, which acts to counteract gravity. (The satellite wants to fly out in a straight line, but gravity forces it to curve towards the Earth.) Consider a communications satellite that needs to be 22,000 km above the Earth's surface. (a) Assuming the satellite travels in a perfect circle, what is the radius of the satellite's travel
