Arrange the equations in the correct sequence to rewrite the formula for displacement, d=vt-1/2at^2, to find a. In the formula, d is displacement, v is final velocity, a is acceleration, and t is time.
TILES
A) 2(vt-d)=at^2
B) a=2(d-vt)/t^2
C) 2(d-vt)=at^2
D) vt-d=1/2at^2
E) d-vt=1/2at^2

You start with $$d = v t - \frac{1}{2}at^2$$and you want to solve for $a$

In general, move all the terms you can move by adding or subtracting, then do multiplication and division to isolate the variable for which you are trying to solve.
In this case, get all the terms which do not have $a$ on one side, then multiply and divide by whatever is in front of $a$ to solve for $a$.

i forgot choice F) a=2(vt-d)/t^2

ooxbrittanyxoo · Answer

would it be D,A,F ?

whpalmer4 · Answer

Yes, D A F is a set of steps which occur in that order while solving for $a$.  Good!
