Does the object return to its starting point? No, 00180: moves away at varying speed, stops, but doesn't return to its starting position. Yes, x = constant again after t = 9s. Object moves away, rests, then comes back. No, there is no negative displacement. There is not enough information to draw conclusion. Choose your answer... A
