A runner is training for an upcoming marathon by running around a 112-m-diameter circular track at constant speed. Let a coordinate system have its origin at the center of the circle with the x-axis pointing east and the y-axis north. The runner starts at (x, y) = (56 m, 0 m) and runs 2.5 times around the track in a clockwise direction.
What is the magnitude of his displacement vector?
.............
Whar is the direction of his displacement vector?
| West |
| East |
| North |
| South |

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 she is blown along the following straight lines: 3.50 km and 45.0° north of west, then 5.10 km and 60.0° south of east, then 2.20 km and 25.0° south of west, then 5.10 km due east, then 1.70 km and 9.00° east of north, then 7.20 km and 55.0° south of west,...

I start walking. The 1st leg of my trip I walk dA = 55 m at θA = 15° south of east. The 2nd leg of my trip I walk dB = 120 m at θB = 21° north of east. On my final leg I walk dC = 75 m at θC = 56.5° north of west. Choose the coordinate system so that x is directed towards the east, and y is directed towards the north. A.) Write an...

george and Paula are running around a circular track. George starts at the westernmost point of the track, and Paula starts at the easternmost point. The illustration below shows their starting positions and running directions. They start running toward each other at constant speeds. George runs at 7 feet per second. Paula takes 50 seconds to run a lap of the track. George and Paula pass each other after 14 seconds. After running for 4 minutes, how far east of...

Solved for displacement, magnitude, and direction of the
vector
An adventurous dog strays from home, runs six blocks east, six blocks north, and five blocks east, five blocks north, and seven blocks west. Assuming that each block is about 100 yd, use the analytical method to find the dog's net displacement vector (in yd). Assume the +x-axis is to the east and the +y-axis is to the north. (Express your answer in vector form.) yd Use the analytical meths to...
