What is the effect of the author's choice to repeat the words absolutely and everything in these sentences?
1. The repetition emphasizes that Newton's theory
is universal and all-encompassing,
2. The repetition creates an astonished tone that
highlights the inventiveness of Newton's theory.
3. The repetition reinforces the idea that Newton's
theory allows scientists to accurately predict
how objects will move.
4. The repetition signals minor shifts in the
meaning of the repeated words in order to
reveal the complexities of Newton's theory.

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.
