Question: One way to attack a satellite in Earth orbit is to launch a swarm of pellets in the same orbit as the satellite but in the opposite direction. Suppose a satellite is in a circular orbit 500 km above the Earth's surface. What would be the speed of such a pellet relative to the satellite? What is the ratio of this relative speed to the speed of a bullet fired from a military rifle (3110 feet per second for an M-16)?
