d=vt+1/2at^2 physics

Question

d=vt+1/2at^2

Students are using the following formula in their high school physics class. They want to rearrange the formula so that 'v' is solved for. What would they get?

Answer 1

d=vt+1/2at^2

d= vt + 1/2 at²

Subtract d from both sides

d-d = vt +1/2 at² -d

0 = vt +1/2 at² -d

Subtract vt from two sides

-vt = vt -vt +1/2 at² -d

-vt = 1/2at² -d

or

vt = d - 1/2at²

Divide by t

v= d/t -1/2 at

Answer 2

As it is written, the solution is pretty straightforward. You must get v on one side of the equation by itself. What do you need to subtract from the right side of the equation to get a term with v on the right side? Then divide both sides of the equation by the which variable to give v alone? This is a problem is algebra 1.
