Concept

Problem: The motions described in each of the questions take place at an intersection on a two-lane road with a stop sign in each direction. For each motion, select the correct position versus time graph. For all of the motions, the stop sign is at the position x = 0, and east is the positive x-direction. (Figure 1)Part A. A driver ignores the stop sign and continues driving east at constant speed.Part B. A driver ignores the stop sign and continues driving west at constant speed.

Part A

If the driver ignores the stop sign and continues to drive towards the east at a constant speed, the graph must have a straight line with a positive slope.
