In the sport of orienteering, participants must plan carefully to get from one checkpoint to another in the shortest possible time. In one case, starting at a particular checkpoint, Sam decides to take a straight path that goes west for 500 meters, and then go northeast for 500 meters on another straight path to reach the next checkpoint. Northeast, by the way, means 45 degrees to both north and east. Between the same two checkpoints, Mary decides to take the shortest distance between the two checkpoints, traveling off the paths through the woods instead. (a) What is the distance that Mary travels between the checkpoints? (Note that Sam travels a total distance of 1000 m, although his speed is probably significantly higher than Mary's.) 387 30

A commuter airplane starts from ar. airport and takes the route shown in Figure P3.19. The plane first flies to city A, located 175 km away in a direction 30.0 north of east. Next, it flies for 150 km 20.0 west of north, to city B. Finally, the plane flies 190 km due west, to city C. Find the location of city C relative to the location of the starling point. Figure P3.19

In an attempt to escape a desert island, a castaway builds a raft and sets out to sea. The wind shifts a great deal during the day and he is blown along the following directions: 2.50 km and 45.0 north of west, then 4.70 km and 60.0 south of east, then 1.30 km and 25.0 south of west, then 5.10 km straight east, then 1.70 km and 5.00 east of north, then 7.20 km and 55.0 south of west, and finally 2.80 km and 10.0 north of east. Use a graphical method to find the castaway’s final position relative to the island.
Figure P3.28 illustrates typical proportions of male (m) and female (f) anatomies. The displacements d1m and d1f from the soles of the feet to the navel have magnitudes of 104 cm and 64.0 cm. respectively. The displacements d2m and d2f from the navel to outstretched fingertips have magnitudes of 100 cm and 86.0 cm, respectively. Find the vector sum of these displacements d3=d1+d2 for both people.

Starting at the origin, a person walks 350 meters in a direction 30.0° South of West, then 570 meters in a direction 35.0° West of North. If the person now wishes to walk in a straight line back to the origin, what must be the magnitude and direction of the displacement?
One afternoon, a couple walks three-fourths of the way around a circular lake, the radius of which is 2.89km. They start at the west side of the lake and head due south to begin with. What is the distance they travel? What is the magnitude of the couple’s displacement? What is the direction (relative to due east) of the couple’s displacement?
Starting from its nest, an eagle flies at constant speed for 3.0 min due east, then 4.0 min due north. From there the eagle flies directly to its nest at the same speed. How long is the eagle in the air?
Most days after lunch, I like to take a stroll around campus ( given it’s not too hot ). Suppose on this day, I walk 4.38 meters 53.50 degrees north-east. If I then walk another 3.24 meters north, how far will I have to walk in a straight line to get back to the physics building where I started?
