Question

So I'm struggling with rearranging kinematic formulas. Does anyone have any steps or something to help.

An example is:
Rearrange D= ViT + 0.5at²
To find a

Answer 1

Rearranging formulas is all about simple algebra rules. Just like when solving for x in an equation, you're just isolating whichever variable you want. I'll work this one out for you and hopefully it'll help, but if you need more explanation, then feel free to comment!

D = ViT + 0.5at² Subtract ViT from both sides

D - ViT = 0.5at² Divide both sides by 0.5t²

`(D - ViT)/(0.5t^(2) ) = (0.5at^(2) )/(0.5t^(2) )` I wrote this step out a little more to show how your fraction will cancel

`(D - ViT)/(0.5t^(2) )`= a I like to flip these around so the single variable is on the right

a =
`(D - ViT)/(0.5t^(2) )`
