How to Rearrange the Formula d=Vft-1/2at^2 to Solve for a

[annjolino]

Homework Statement

rearrange the formula d=Vft-1/2at^2 to solve for a

Homework Equations

d = Vft-1/2at^2
d+ 1/2at^2 = Vft
1/2at^2 = Vft-d
1/2a = Vft-d / t^2

then does a = 2 (Vft-d / t^2)

Hi annjolino!

What I expect you meant is right …

but what you've written is wrong …

should be a = 2 (Vft-d) / t^2 …

you'll lose marks in the exam if you get brackets in the wrong place!

(and you could have missed out the line d+ 1/2at^2 = Vft)
