comment Linear field approximation to gravitation
Good question, but it would help if you could edit the question to include a bit of the context from the PDF file (equations 11.1 and 11.2, in particular) so people don't have to click the link to understand what you're asking about.

comment What happens in a car crash?
@user45198 Sure, we understand this is not a homework assignment, but any sort of question where people just ask us to calculate something for them is what we call "homework-like", and is off topic here. Better questions are those that ask about some conceptual misunderstanding - so, for instance, you calculated the answer yourself but you're confused about why some particular step works.

comment What happens in a car crash?
@Photon well, but if that's all user45198 is asking, this would qualify as a no-effort homework-like question under our policy. I want to think there is something more here.

comment What happens in a car crash?
Hi user45198, and welcome to Physics Stack Exchange! It's not clear to me what you're actually asking here; could you clarify that? Are you asking whether it's possible that the car behind you sped up your car to faster than it was already moving?

comment How fast would a truck have to go to pull a pedestrian onto the road?
Or, questions like "I tried method A but I can't understand how to get from step B to step C" are also good. Note that there are many ways to improve a question like this, and what I've outlined in the last comment is only one of them, so don't feel like you have to follow that exact template. I'd suggest checking some of the examples of good questions in our homework policy for inspiration.

comment How fast would a truck have to go to pull a pedestrian onto the road?
What would really help this question is if you were to show some effort to solve it yourself. In a nutshell, we tend to react badly to questions that say only "calculate this thing for me" or "tell me how to do this" (which is kind of what you're doing). A better question would be if you say something like "I searched Google to see if this had been done before, I tried calculating it using method X but that didn't work because Y, and then I tried method Z but that didn't work because Z'. Is there some other method that will work?"

Don't worry about it this time. Just save your edits in the future for when you really need to fix something important. And when you have a good reason to make an edit, go through and make all the little improvements you can find at the same time, all as part of the same edit.

Hi user43880; please don't edit your question so often. Every edit bumps the question up to the top of the front page, taking attention from other deserving questions.
