PLS HELP I'LL MARK BRAINLIEST The figure shows four forces exerted on a box.

A square is shown with an arrow pointing up labeled F3, an arrow pointing right labeled F1, an arrow pointing down labeled F4 and an arrow pointing left labeled F2

If F1 is equal to F2 and F4 is greater than F3, which statement is correct? (3 points)

a
An unbalanced force will move the box up.

b
An unbalanced force will move the box down.

c
Several balanced forces will keep the box stationary.

d
Several balanced forces will keep the box moving towards the right.

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.
