A person walks to the right along a straight-line path with a steady velocity for "6" seconds, stops and stands still for "6" seconds, then reverses directions and walks to the left at a steady velocity twice as great as their motion to the right until they return to where they started. Make a prediction of their position-time and velocity-time graphs.

PhET to check your predictions. Compare your predictions to the simulated outputs and make the appropriate corrections.
