The velocity vs. time graph for an object moving along a straight path is shown in the figure below. A function is plotted on a coordinate plane, with the horizontal axis labeled t (s) ranging from 0 to 21 s and the vertical axis labeled v (m/s) ranging from −9 m/s to 9 m/s. The function enters the viewing window at (0, −8) and goes horizontally rightward to the approximate point (5, −8). Then the function curves upward and extends up and right in a straight line to the approximate point (15, 8). The function then curves rightward and goes horizontally rightward to the point (20, 8), where the function ends. (i) Find the average acceleration of this ob
