How exactly does an asteroid travel between solar systems by its own impetus?

Gravity.
Well, how did it achieve enough velocity to escape the gravity in it's original solar system?

Well, it may have never established a stable orbit in an "original solar system" in the first place. A forming solar system is a chaotic place, lots of collisions and near misses. Staggering amounts of energy can be involved. It could also be on the other end of the time scale - something ejected during the end of a solar system. A supernova ejects entire solar systems' worth of materials... it's how we got here in the first place!
Any random asteroid encountering Jupiter at the wrong angle and speed can be flung out into deep space.

It looks like the Heavens are taking pot shots at us.
Well, I'm kicking myself that we're not up there on it.
85 times the distance to the moon it passed, that's almost a quarter the distance to the Sun.
21.5 million miles. Probably take two years to get there. And, that's if we had something ready that we could just point and shoot.
At 196,000 mph, this is three times our speed around the sun we're going to have to catch up with it, deploy the far intercepts, strap on engines, turn that baby around and let's study it. I bet it was the crust of some planet that was so torn it launched on a trajectory out of it's solar system.
Do you want to calculate how far it will get before we have the technology to catch up with it? 1.752 Billion miles or 188 AU per year. There are nearly sixty four thousand Astronomical Units in a light year, so in 335 years it should be one light year distant.
We should get a good mark on it's trajectory, it would make a hot yacht, 400 meters long, that's a quarter of a mile.
Is it going to stay in our solar system? I haven't read enough about it to know if it's moving to fast for the sun to capture it.

It's hard not to think of Arthur C Clarke's Rendezvous with Rama, when considering Oumuamua.

My thought exactly... and likely the first thing on the mind of all of these scientists... though I guess they don't want to get people's hopes up by just calling it Rama.
Yeah, still it would have been cool for them to give a nod to old Arthur C and name it Rama. Easier to pronounce too.
True, but they are optimists. They are saving "Rama" for the real deal.

Perhaps. But the universe is full of matter that is not trapped in solar gravity wells. This object, as it turns out, is now trapped in ours. The object is traveling 196k mph, while the escape velocity of the Sun is about 1.4m mph.
No, it is not trapped in ours. It is on a hyperbolic course, and is already on an outbound course. It has picked up speed thanks to the slingshot effect, but since it has already passed the sun it is actually slowing down again. It will be leaving the system at about the same speed it entered it at.
It is estimated that it entered the system at 26 km/s, reached a peak speed of 88 km/s as it passed the sun and Mercury, and will depart at 26 km/s.
And you are way off on your escape velocity. Voyager I has already exited the Solar System, and is passing through interstellar space. And it is only traveling at 17 km/s.
