Problem 22PE

A farmer wants to fence off his four-sided plot of flat land. He measures the first three sides, shown as A, B, and C in Figure 3.62, and then correctly calculates the length and orientation of the fourth side D. What is his result?

Step-by-Step Solution:
Step 1 of 5<p>We will use the vector addition formula to calculate the length and orientation of  D. Step 2 of 5<p>From the vector addition formula, we can write that

To calculate , first we will decompose each vectors in  and  components. Then add the components to calculate the  and  components of resultant vector. From this component calculate the magnitude and direction of the .

Step 3 of 5<p>Vector  is making  with the  axis, hence the  and  components are,

And

Vector  is making  with the  axis, so the angle with  axis is . Hence, the  and  components are,

And

Vector  is making  with the  axis, hence, the angle with  axis is . Hence, the  and  components are,
