Chapter 2, Problem 55P

To determine

To construct: The velocity versus time graph for the object whose displacement as a function of time.

Explanation of Solution

Given:

The given figure is shown below.

  

For the given graph, the velocity versus time graph is shown below.

  

Figure 1

Here as shown in the graph above, object moves with a constant speed till $20\text{ sec}$ then slope increases rapidly till $27\text{ sec}$ and it decreases till $44\text{ sec}$ and then again increases till $50\text{ sec}$ .

Conclusion:

The graph is shown in Figure 1.
