Repeat Exercise 3.16 using analytical techniques, but
Chapter 3, Problem 17(choose chapter or problem)
Repeat Exercise \(3.16\) using analytical techniques, but reverse the order of the two legs of the walk and show that you get the same final result. (This problem shows that adding them in reverse order gives the same result—that is, \(B+A=A+B\).) Discuss how taking another
path to reach the same point might help to overcome an obstacle blocking you other path.

B+A=A+B
ANSWER:
Step 1 of 4:
We are walking 25.0 m straight west then 18.0 m straight north. We need to walk more distance to reach the final point. But we can go to the final point by taking a short way through the hypotenuse of the triangle. Our aim is to find B+A and the direction of the path taken. The magnitudes of the displacement vectors are given by
B = 25.0 m
A = 18.0 m
