Question

using the information from question 18, calculate the magnitude of laura’s average velocity for the trip. formula: v = d / t d stands for displacement a. 1.00 m/s b. 1.08 m/s c. 2.16 m/s d. 3.16 m/s question 20 * 20. in the diagram to the right, the solid line surrounded by the dotted line represents the ____; and the dotted line by itself represents the ____. a. speed; velocity b. rate; velocity c. distance; displacement d. displacement; distance a b c

Explanation:

Step1: Recall the concept of average velocity

Average velocity is given by $v=\frac{d}{t}$, where $d$ is displacement and $t$ is time. But we are not given values of $d$ and $t$ here. Since we cannot calculate without values, we assume we are to answer based on concepts for the multiple - choice nature of the question. For the second part, recall the difference between distance and displacement.

Step2: Analyze question 20

Distance is the total length of the path traveled, and displacement is the straight - line distance from the initial to the final position. The solid line (the actual path) represents distance and the dotted line (straight - line between start and end) represents displacement.

Answer:

1. Cannot be determined for the first question (as no values of displacement and time are provided).
2. C. Distance; Displacement
