One way to attack a satellite in Earth orbit is tolaunch a swarm of pellets in the same orbit as the satellite but inthe opposite direction. Suppose a satellite in a circularorbit 500 km above Earth's surface collides with a pellethaving mass 4.0 g.

(a) What is the kinetic energy of the pellet in the reference frame of the satellite just before thecollision?

(b) What is the ratio of this kinetic energy to the kineticenergy of a 4.0 g bullet from a modern army rifle with amuzzle speed of 950 m/s?
