The image shows how Earth orbits the Sun Points W and X are the same distance from the Sun. A) Earth is speeding up at W and slowing down at X
because the force on Earth is greater at W than at Х

B) Earth is slowing down at W and speeding up at X
because the force on Earth is greater at W than at Х

C) The speed of Earth is the same at Was at X
because the force on Earth is the same at Was at Х

D) The speed of Earth is greater at W than at X
because the force on Earth is greater at W than at Х

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

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.
