Homework Help Overview

The discussion revolves around rearranging the equation v² = u² + 2as to solve for 's', which represents displacement in kinematics.

Discussion Character

  • Mathematical reasoning, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to isolate 's' but struggles with the rearrangement. Some participants suggest starting by isolating "2as" and question the approach of moving 's' to the other side of the equation. There is also a mention of difficulties in formatting fractions on the forum.

Discussion Status

Participants are actively engaging with the problem, with some providing guidance on isolating terms and sharing tips about using formatting tools on the forum. There is a sense of progress as the original poster expresses understanding after receiving input.

Contextual Notes

The original poster expresses uncertainty about the correct rearrangement and formatting of equations within the forum's posting system.

I have been trying but i can't quite figure out how to rearrange this so that 's' (displacement) is the subject. Please help me figure this out.

Sorry if this is in the wrong place.

What have you gotten so far?

Start by isolating "2as" to one side.
 
Mostly what i had tried involved me immediately trying move 's' to the other side (so eg. v²/s=u²+2a), which hadnt been working for me. So, by isolating 2as, would this be correct as what i end up with:

v²-u²
_____ = s ?

2a

(Ordinarily 's' would be on the other side, but i couldn't work out how to do fractions on this forum).

So, is that pretty much right?
 
Yep, you got it. :biggrin:

You can use Latex for it on the advanced posting screen, the button([tex]\Sigma[/tex]) is on the upper right:

[tex]s = \frac{v^2-u^2}{2a}[/tex]

Awesome, now that I understand this the rest of my work is easy. Thanks!

Thanks for telling me about this, many forums i visit I've needed something like this, but never known how to use it.

No problem, just take a little bit to get used to. I'm still trying to figure it out too.
