The average velocity for our robot car was 0 cm/s. The formula for velocity is displacement/time. Our displacement was 0 (because it ended up in the same place). But as the robot car was going forward, the velocity was approximately 8.88 cm/s north. then for three seconds, the robot car stayed stationary at a velocity of 0 cm/s. Then the car begins to move back to its origin at an average velocity of 8.88 cm/s south.

Off to a great start. You analysis should consider how the object’s movement is reflected in the graph (i.e. what characteristics of the graph support your description). Otherwise, nice job.
