Velocity over the ground (?) ("beholden fart" in my native language) in a unit of nautical miles per 56 hours, would be the closest I can think of, but it doeen't make much sense. Peter S/Y Anicula |

Jax,
You're doing it again. A LINE from the STARTING POINT to the finish LOCATION isn't a point. The POINT is on your head. Read the question again (with an open mind) analysis. A course was set. It was Sailed and the finish wasn't where the start was, due to Drift. That difference can be connected with a line. CONNECTED WITH A LINE not a DOT H to O, my friend H to O Ole Thom |

Vectors alway have magnitude
Magnitude measured in what units, Jax? Ole Thom |

answer: a resultant
Scout "Bart Senior" wrote in message . .. You sail directly East for 14 hours, then South for 14 hours, and then West for 14 hours, and then North again for 14 hours. Now if you draw a vector between your starting position and your final position. What would you call that vector? |

BTW, your question was (kinda) about DRAWING a vector, and I still call that a dot :-) Cheers!

old dude, it seems you do not understand the term "vector" even yet. the
question you ask is not applicable. Vectors alway have magnitude Magnitude measured in what units, Jax? Ole Thom |

Should have been "unless you cross the equator exactly after the first
21 hours" instead of 7. I thought you went North first. My teacher apparently forgot to tell me to read the question thoroughly before answering. Maybe I should comment a bit further on the "geometrical component". It could be defined as a trigonometrically function of your start-latitude and your speed over the ground. Hint: A "parallel", the circle that consists of al points at a given latitude (for instance 56 degrees North), is smaller (has a lesser circumference) than any parallel closer to the poles and larger than any parallel closer to equator, but they are all crossed by the same number of longitudinal.

Yet another correction:
It is of course the parallels closer to equator that are the larger ones, and the ones closer to the poles that are smaller. But you already knew that I meant the opposite of what I wrote, didn't you? Hint: A "parallel", the circle that consists of al points at a given latitude (for instance 56 degrees North), is smaller (has a lesser circumference) than any parallel closer to the poles and larger than any parallel closer to equator, but they are all crossed by the same number of longitudinal.
