Chapter 14.2, Problem 4WE

To determine

To find: The representation of the given vector in the component form.

Answer to Problem 4WE

The component form is $6\overrightarrow{j}$ .

Explanation of Solution

Given:

The $\overrightarrow{AB}$ vector is to identified.

The given diagram is shown in Figure 1

  

Figure 1

Calculation:

From the given graph, the vector $\overrightarrow{AB}$ is obtained as,

  $\begin{array}{c}\overrightarrow{AB}=\left[\left(-3\right)-\left(-3\right)\right]\overrightarrow{i}+\left[4-\left(-2\right)\right]\overrightarrow{j}\\ =6\overrightarrow{j}\end{array}$

The component form is $6\overrightarrow{j}$ .
