One way to attack a satellite in Earth orbit is to launch a swarm of pellets in the same orbit but in the opposite direction. Suppose a satellite in a circular orbit 500km above Earth's surface colides with a pellet having a mass of 4g.
What is the KE of the pellet in the reference frame of the sallite
R = 6.87x10^6m
G = 6.67x10^-11
Mearth = 5.98x10^24
M of pellet = .004kg
For this...I tried finding the velocity of the Satellite...V = (squareroot (GMearth/R)), which turned out to be 7620m/s
I know that the pellet is going in the oppsite direction..so that would make the speed of the pellet -7620m/s
then I used the KE equation. K = .5mv^2 and got the answer to be 116118J, which isn't the right answr...
HELP!
