Describe the student's trip in words that would be understandable to someone who is not taking physics. Give the person information about where the student goes and how fast the student moves to get there (no numbers are needed, but give comparisons like "faster" or "slower").
Solution
System: The student will be treated as a point particle.
Interactions: Not relevant for this model.
Model: One-Dimensional Motion with Constant Velocity.
Approach: The One-Dimensional Motion with Constant Velocity gives as an alternate representation the fact that a constant velocity can be represented as the slope of a linear position versus time graph. The graph we are given in the problem introduction is not linear overall, but it can be split into linear segments, as denoted by the different colors in the version given here:
