A vehicle starts to move from the rest gets an acceleration of 5 m/s2 within 2 seconds. Calculate the velocity and distance covered by the vehicle within the given time.

I. Final velocity, V = 10m/s.

II. Distance, S = 10m.

Explanation:

Given the following data:

Acceleration = 5m/s²

Time = 2 seconds

Since the vehicle starts from rest, initial velocity = 0m/s

To find the final velocity, we would use the first equation of motion.

V = U + at

Substituting into the equation, we have

V = 0 + 5*2

V = 0 + 10

V = 10m/s.

Now, to find the distance covered, we would use the second equation of motion.

S = ut + ½at²

S = 0*2 + ½*5*2²

S = ½*5*4

S = 20/2

S = 10m

it is called kinetic energy

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.
