Homework Help Overview

The problem involves two boats, P and Q, with given position vectors and velocities. The task includes showing the velocity of boat P and determining the time when boat Q is northeast of boat P. The context is rooted in vector analysis and motion in a two-dimensional plane.

Discussion Character

  • Mixed

Approaches and Questions Raised

  • Participants discuss the calculation of the velocity of boat P and question the wording of the problem regarding the positioning of boat Q relative to boat P. There are attempts to clarify the meaning of "northeast" and the implications of the position vectors.

Discussion Status

Some participants have provided hints and suggested methods for approaching the problem, while others express confusion about the wording and the need for a vector diagram. There is ongoing exploration of the relationships between the position vectors and velocities of the boats.

Contextual Notes

There are mentions of potential typos in the original problem statement, and participants are considering the implications of these discrepancies on their calculations. The discussion reflects a lack of consensus on the correct interpretation of the problem setup.

Put ##t=1## in your vector. Does it point NE? How about ##t = 2## or ##t=3## etc. The question is, is there any value of ##t## that gives a vector that points NE.
I get it now
I have to find out by changing t which changes the values inside the bracket
Hence giving magnitude to i & j

I completely understand
Thank you very much

(2+t)i + (10t-15)j

2+t=10t-15
t-10t=-2-15
-9t=-17
t=-17/-9
t=1.889

So that's 1hr 53min 20sec past noon
Thank you very much
And thank you for being so patient with me

You are welcome. I'm curious what math courses you have had or are taking now.

Non actually
I just find questions here and there and try to attempt them
