The position vs. time graph below shows the position of a dog as it chases after a squirrel. Draw the corresponding velocity vs. time graph, as well as the corresponding acceleration vs. time graph. You may assume constant acceleration within each interval on the graph (though the value of that acceleration may differ from one interval to the next).
