82 Mt. Lafayette hike. Eigure 3.19 shows a trail 5.8 km long, leading from a trailhead (elevation 1770 ft) to the summit of Mt. Lafayette (elevation 5250 ft) in New Hampshire. Sara hikes the trail. What are the (a) magnitude L and (b) elevation angle (relative to the horizontal) of Sara's displacement for the hike? (Measure the component in the plane of the map by laying the edge of a sheet of paper next to the line in the map, marking off the line's length d, and then using the scale on the map.)
