2.21. Set Up: Values of at time t can be read from the graph: and is constant when x versus t is a straight line. Solve: The motion consists of constant velocity segments. to 4.0 s: to 10.0 s: to 18.0 s: The graph of versus t is shown in Figure 2.21. Figure 2.21 Reflect: is the slope of x versus t . 2.22. Set Up: The instantaneous acceleration is the slope of the versus t graph. Solve: The graph is horizontal, so The graph is a straight line with slope The graph is a straight line with slope 2.23. Set Up: Solve: (a) 0sto2s : 2sto4s : 4sto6s : 6sto8s : 8 s to 10 s: 10 s to 12 s:
