So i'm struggling with rearranging kinematic formulas. does anyone have any steps or something to .

an example is:
rearrange d= vit + 0.5at²
to find a

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

   I wrote this step out a little more to show how your fraction will cancel

= a    I like to flip these around so the single variable is on the right

a =
