You set out driving due north at 10m/s in your car. After 20s at this velocity, you accelerate for 10s until reaching 30m/s, merging onto a highway. You continue at this velocity until reaching your exit, 40s after your merged onto the highway, and then decelerated until coming to a stop 20s later.

Part 1: Graph the velocity-time graph for this journey on paper and embed a picture here.

A. Find the average acceleration during each of the four parts of this journey by calculating the slope of each line segment in your graph.

B. Find the net displacement during each of the four parts of this journey by finding the area under each line segment in your graph

C. Find the net displacement for the entire journey

Part 2: Graph the position-time graph for this journey on paper and embed a picture here.

A. Plot the position-time graph for this journey

B. Find the slope of each of the four line segments in your position-time graph. What do these represent?
