Given the question: Answer the following question given this paragraph: Example 2.17 Determining Average Velocity from a Graph of Displacement versus Time: Jet Car Find the average velocity of the car whose position is graphed in Figure 2.47. Strategy The slope of a graph of x vs. t is average velocity, since slope equals rise over run. In this case, rise = change in displacement and run = change in time, so that. Q: In a displacement graph, the slope of the line is the average what? Choices: - direction - speed - time - velocity A:
The answer is:
velocity
