Speed, Velocity, and Graphs (1D)

Here again is a hockey puck bouncing off a wall and returning to its original starting point where it is stopped as shown in the animation (position is shown in meters and time is in seconds). A graph of position versus time is shown. Sketch the graph in your notes.

Questions

1. Using the graph, how can you visually show the average velocity of the puck during the time it is in motion? Begin
2. Using the graph, how can you show the instantaneous velocity of the puck at t = 3.0 seconds?
