Textbook Question
Chapter 3, Problem 16PE

Solve the following problem using analytical techniques: Suppose you walk 18.0 m straight west and then 25.0 m straight north. How far are you from your starting point, and what is the compass direction of a line connecting your starting point to your final position? (If you represent the two legs of the walk as vector displacements A and B, as in

Chapter 3, Problem 16PE, Solve the following problem using analytical techniques: Suppose you walk 18.0 m straight west and

Note that you can also solve this graphically. Discuss why the analytical technique for solving this problem is potentially more accurate than the graphical technique.

Solve the following problem using analytical techniques: Suppose you walk 18.5 m straight west and then 26.0 m straight north. How far are you from your starting point, and what is the compass direction of a line connecting your starting point to your final position? (If you represent the two legs of the walk as vector displacements A and B, as in the figure below, then this problem asks you to find their sum  R = A + B.  Give the direction in degrees north of west.)
Solve the following problem using analytical techniques: Suppose you walk 18.0 m straight west and then 25.0 m straight north. How far are you from your starting point, and what is the compass direction of a line connecting your starting point to your final position? (If you represent the two legs of the walk as vector displacements A and B, as in Figure 3.58, then this problem asks you to find their sum R=A+B.)
Proceeding from landmark A, a vehicle moves along city streets 10 km north, then 14.2 km northeast, and finally 2 km south, and arrives at landmark B.  What is the distance traveled, and the magnitude of the displacement between the two landmarks? From the previous problem, what angle east of north does the displacement vector lie?
