Shouldn't this have some thrust limits? I'm not sure if they are added later(I've only seen the first example), but it would make the problems more realistic, interesting and related to control theory.
I believe there are hidden ones.

My inner child of Doc Brown and Wernher von Kerman says, it's time to develop non-newtonian fuel sponges, which would release fuel if squeezed gently and steadily, but behave like solid if things start shaking too much, preventing sloshing.
Or maybe giant syringes? There can't be sloshing if there is no free space because top of cylinder just moves to adjust volume.
You do get baffles in liquid fuel tanks to cut down the effect, and some people have tried flexible bladders inside the rigid tanks for a similar reason but they don't work well with cryogenic fuels.

Could you elaborate please.
Sure! So in many, if not most, contemporary Information Retrieval (IR) problems, there is a total document set larger than could be explored on an interactive basis and so the data structures get laid out in such a way that with some probability north of a coin, you’ll find “better” documents in the “front” half. This is hand-waving a lot of detail away, so if you’d like me to go into some detail about multi-stage ra…

This actually makes perfect sense, so I'm hoping some rocket scientist will come and explain what are the "devils in the details" that prevent rockets from being built like this.
And then you'd gave to over engineer the rocket iself to not break when tipping over, not just the fuel tanks.

#107I put in large constant forces, but the acceleration doesn't seem to depend on the force (on the inclined car level)

Show code or it didn't happen :)
it's pretty trivial! erghea -400 oybpx.k-40 oybpx.qk; (not that rot13 really obscures anything here!) The rest of the puzzles get pretty interesting, I shouldn't have just stopped on the first and spent all the time optimizing it. If the author sees this thread it would be fun if you could disturb the dynamics with the mouse after completing one. I wanna watch the ball catching piston right the ball if I poke it.
