Taking a Hike A hiker begins a trip by first walking 19.0 km southeast from her car. She stops and sets up her tent for the night. On the second day, she walks 44.0 km in a direction 60.0° north of east, at which point she discovers a forest ranger's tower. w-OE y (km) Tower B x (km) Can 45.0° 60.0° (a) Determine the components of the hiker's displacement for each day. SOLUTION Conceptualize We conceptualize the problem by drawing a sketch as in the figure. If we denote the displacement vectors on the first and second days by A and B, respectively, and use the -Select--v as the origin of coordinates, we obtain the vectors shown in the figure. The sketch allows us to estimate the resultant vector as shown. Categorize Drawing the resultant R, we can now categorize this problem as one we've solved before:-Select- already solved if we are careful to conceptualize them. Once we have drawn the displacement vectors änd categorized the problem, this problem is no longer about a hiker, a walk,…
