Caleb is walking in a straight line. The distance he travels can be expressed by

$v_0 t + 1/2 a t^2$ , where

$v_0$ is his initial speed,

$t$ is the amount of time he walks, and

$a$ is how much he accelerates in the direction he is walking. If Caleb does not accelerate at all, what does this imply?

No conclusion can be made without knowing for how long he walks.
That he stands still (does not walk).
That he will not walk very far.
That he walks at his initial speed the entire time.
