Write an equation describing the velocity at any time for an object given an initial velocity of Vo in the positive direction which is acted by an acceleration in the negative direction.

Question

Write an equation describing the position at any time for an object starting from an initial psoition Xo with an initial velocity Vo in the positive direction, which is acted on by an acceleration in the negative direction.

Answer 1

v(t) = Vo + at
where a is negative, in this case.

s(t) = Xo + Vot + 1/2 at^2
where a is negative

If all you wanted was the formulas, why not just look in your text book? They are presented there. I'm sure.
