The official’s truck in Fig. 2.2 is at at and is at at ${\mathit{x}}_{\mathbf{1}}\mathbf{=}\mathbf{277}\mathbf{}\mathbf{\text{m}}$, at ${\mathit{t}}_{\mathbf{1}}\mathbf{=}\mathbf{16}\mathbf{.}\mathbf{0}\mathbf{}\mathbf{\text{s}}$, and is at ${\mathit{x}}_{\mathbf{2}}\mathbf{=}\mathbf{19}\mathbf{}\mathbf{\text{m}}$at ${\mathit{t}}_{\mathbf{2}}\mathbf{=}\mathbf{25}\mathbf{.}\mathbf{0}\mathbf{}\mathbf{\text{s}}$. (a) Sketch two different possible x-t graphs for the motion of the truck. (b) Does the average velocity${\mathit{v}}_{\mathbf{a}\mathbf{v}\mathbf{-}\mathbf{x}}$ during the time interval from${\mathit{t}}_{\mathbf{1}}$ to${\mathit{t}}_{\mathbf{2}}$ have the same value for both of your graphs? Why or why not?
