Amass of 2.50 kg is in a gravitational field of 14.0 n/kg. what force acts on the mass?

So then the force acting on the mass for this gravitational field is 35N

Explanation:

The gravitational field is defined as the force that acts on an object of mass m. By definition we have that :

from the second law of Newton.

In our case the value of a represent the acceleration or the gravitational field, so then the expression for the gravitational field is:

For this case we know that and

So if we replace and find F we got:

So then the force acting on the mass for this gravitational field is 35N

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.

i would say
