Just sharing resources: This is a graph I had my students working with in class after struggling with a similar homework problem.
- I first had students identifying whether points A-I were moving to right, to the left, or not moving.
- I then had students identifying whether sections 1-7 were speeding up, slowing down, or moving with constant speed.
- I then had students work on constructing a velocity vs. time graph.
Lots of other questions could be asked.
