<h2>
The magnitude 24 (
) of the acceleration of the particle when the particle is not moving.</h2>
Explanation:
Given,
A particle moving along the x-axis has a position given by
m ........ (1)
To find, the magnitude (
) of the acceleration of the particle when the particle is not moving = ?
Differentiating equation (1) w.r.t, 't', we get

⇒
....... (2)
⇒ 
⇒ 
⇒ t = 2 s
Again, differentiating equation (2) w.r.t, 't', we get

Put t = 2, we get

Thus, the magnitude 24 (
) of the acceleration of the particle when the particle is not moving.

1. According to person standing on ground ~
2. According to The car ~
- The person is not in motion
3. According to the Seat ~
- The person is not in motion
4. According to another person on ride ~
- The person is not in motion
5. According to the track ~
6. According to the Sun ~
I hope that's what you were looking for, goodluck for your assignment ~
Well, st first we should find <span>initial momentum for the first person represented in the task which definitely must be :
</span>

And then we find the final one :

Then equate them together :
So we can get the velocity, which is

In that way, according to the main rules of <span>conservation of momentum you can easily find the solution for the second person.

The object that had the most 1000 ton weight has the most momentum
