I recommend sticking a long piece of conductor to the satellite,
rather than banging on it with spaceships (;-))

As for the starship, it should treat asteroids like mines, and assume
someone is trying to "sink" them.

If you own a 50 ton spaceship, please do not intentionally hit any
asteroids or other objects with it. What you get is smaller objects
heading in different directions at different velocities, none of
which are all that predictable, and in total more danger to objects
in space than before and still significant danger to ground objects.
What you want is to turn it harmless. This is done by gently
attaching to it and then giving it a controlled push.
I've been curious about what one could do over time just using the
pressure of light from the ground, or enough light to
gassify material to add delta V, however high power devices for this
would also be effective weapons.
Thanks

So, what would happen if we hit one of these (3 new ones discovered
yesterday) with 50tons of starship, at 15 klicks per second? [1]

the three new ones, discovered and announced a day or three back:
https://www.smithsonianmag.com/smart-news/three-near-earth-asteroids-were-hiding-in-the-suns-glare-180981055/
(Atira class are rocks within earth orbit. They are very hard to see,
probably overly baked (low on volatiles), and get bright sun all the
time)
[1] I'm very inspired by DART, but afraid to do the math for this
tonnage and speed. (anyone? there's a LOT of zeroes... ) I have
project ploughshare on my mind, except kinetic, and it's less
deflection on my mind than reducing a rubble pile to rubble,
identifying the good pieces, and bringing them back.
