In the figure below is shown a snapshot of a piece of an elastic spring on which a pulse is traveling. Each square of the grid represents 1 cm. In a video of the motion of the pulse, the pulse is observed to move a distance of 2 cm in 0.04 seconds.
Three pieces of tape are attached to the spring. They are marked by small circles in the figure and are labeled A , B , and C .
On the graphs below, graph the velocity of each of the 3 pieces of tape as the pulse moves past them. Draw the graphs carefully and indicated the scales you are using for your axes.
