So this is meters per second right over here, and this is seconds in this axis. At exactly time zero, this object is traveling at five meters per second. And we could say to the right. It has a velocity of positive five meters per second. But then it keeps decelerating at a constant rate. So five seconds into it, right at five seconds, the particle has no velocity, and then it starts having negative velocity, which you could interpret as moving to the left. So let's think about a few things.
