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.
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 C. A driver, traveling west, slows and stops at the stop sign.
PART D. A driver, after stopping at the stop sign, travels east with a positive acceleration.
