Plugging these into our quadratic formula we get x -2 - sqrt 22 - 413 21. If an object is traveling in a straight line with an initial position of s an initial velocity of v and a constant acceleration of a then its position s at time t after that initial time is given by the formula. Just as a side note the expression Δ d v is not well defined because you are diving by a vector the velocity.
