The question is in the image. Ignore the color underneath each possible answer, that is what I am supposed to do(I am supposed to color in). The question is hard for me.

Answer:


v_0=v_f-at

Explanation:

Given equation:


a=(v_f-v_0)/(t)

To solve for v₀, rearrange the equation to isolate v₀.


\textsf{Multiply both sides by $t$}:


\implies at=(\left(v_f-v_0\right)t)/(t)


\textsf{Cancel the common factor $t$ on the right side}:


\implies at=(\left(v_f-v_0\right)\diagup\!\!\!\!t)/(\diagup\!\!\!\!t)


\implies at=v_f-v_0


\textsf{Add $v_0$ to both sides}:


\implies at+v_0=v_f-v_0+v_0


\implies at+v_0=v_f


\textsf{Subtract $at$ from both sides}:


\implies at+v_0-at=v_f-at


\implies v_0=v_f-at

Solution


\large\boxed{v_0=v_f-at}

Answer:


  • v_o=v_f-at

=================================

Given equation


  • a=\cfrac{v_f-v_0}{t}

Solve it for
v_0

Step 1

Multiply both sides by t to get rid of fraction:


  • at=v_f-v_o

Step 2

Find
v_0 by rearranging the terms:


  • v_o=v_f-at

Correct choice is the last one.
