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 in a circular orbit 580 km
above Earth's surface collides with a pellet having mass 7.2 g.
(a) What is the kinetic energy of the pellet in
the reference frame of the satellite just before the collision?
(b) What is the ratio of this kinetic energy to
the kinetic energy of a 7.2 g bullet from a modern army rifle with
a muzzle speed of 1200 m/s?

1 What is the Earth's orbital speed as it orbits the Sun. Take the Earth/Sun distance to be 93 million miles (taking the Earth's orbit to be circular), the mass of the Earth to be 5.97 X 102 kg and the mass of the Sun to be 1.987 X 10*0 kg. Solve this problem using Newton's 2nd law directly 2. A 55.7 kg mass is lifted (at a constant velocity) from the ground to a vertical height of 1275 m....
