Homework Help Overview

The discussion revolves around a physics homework problem involving two bicyclists traveling to a campground via different routes. The problem requires understanding vector distances and directions based on their respective paths.

Discussion Character

  • Exploratory, Problem interpretation, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to apply the Pythagorean theorem to determine distances but expresses uncertainty about their calculations. Some participants question the clarity of the assignment's question, while others suggest that a visual representation might aid in understanding the problem.

Discussion Status

The discussion is ongoing, with participants clarifying the specific questions related to the cyclists' distances and directions. There is a recognition that understanding the first cyclist's path may assist in solving for the second cyclist's route.

Contextual Notes

Participants are navigating assumptions about the problem setup and the relevance of the distances traveled by each cyclist. The original poster indicates a potential misunderstanding of the assignment's requirements.

Hello, having a little trouble on an intro to physics homework problem.

Homework Statement



Two bicyclists, starting at the same place, are riding toward the same campground by two different routes. One cyclist rides 1050 m due east and then turns due north and travels another 1430 m before reaching the campground. The second cyclist starts out by heading due north for 2000 m and then turns and heads directly toward the campground.

Homework Equations


Pythagorean theorem?

The Attempt at a Solution


I tried using the theorem (used 2000 m as C^2 and 1050 m as A^2 since that is the distance that the first biker traveled), doesn't seem to work out.
I found out that the magnitude for the first biker is 1776? I believe that has to have some relevance to solving this problem.

Thanks for the help.

What exactly is the question of the assignment?
 
Ok, ignore this.. I guessed (probably wrongly) what the question was!
 
oh stupid me..lol

the question is

At the turning point, how far is the second cyclist from the campground?

i guess if i can somehow figure the first one out i can figure the second part which is...

What direction (measured relative to due east) must the second cyclist head during the last part of the trip?
 
All you have to do is draw a 'trapezoidal' sketch and remember what a smart old greek said.
