Homework Help Overview

The discussion revolves around a physics problem involving two concurrent vectors, F and G, acting on a particle. The problem provides specific magnitudes and angles for vector F and the resultant vector R, asking for the angle of vector G.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the need for visual representation to understand the problem better. There are mentions of different methods to approach the solution, and one participant requests clarification on how to visualize the vectors involved.

Discussion Status

Some participants have offered guidance on how to set up the problem using a coordinate system. There is an acknowledgment of the need for the original poster to engage more with the problem to facilitate further assistance. The discussion is ongoing with varying levels of understanding and interpretation.

Contextual Notes

The original poster mentions an upcoming exam and expresses uncertainty about the problem, indicating a need for foundational understanding rather than just a solution. There is a suggestion to avoid feeling discouraged while seeking help.

how would i solve this?

"Two vectors, F and G, act concurrently and simultaneously on a particle. If F=20m at 30 degrees and the resultant, R, of the vectors is 50m at 45 degrees, the angle of force G is"?

thanks for making me feel stupid :D
 
Physics news on Phys.org
cough ?
 
this is the right forum, no?
 
You close your post with "thanks for making me feel stupid" and then are suprised no one wants to respond? Believe me, we are not responsible for how you feel!

"Two vectors, F and G, act concurrently and simultaneously on a particle. If F=20m at 30 degrees and the resultant, R, of the vectors is 50m at 45 degrees, the angle of force G is"?

Did you read "Read this before posting" before posting?

Since we don't want to make you feel stupid, we ask that you make some effort and show us what you have done- so that we will know that we are not just doing your homework for you and also so that we will have a better idea of what kind of help you need.

I know at least two very different methods of solving this. I DO NOT know which is appropriate for you.
 
im sorry for misleading you guys, i didnt really think you would make me feel stupid, but that was just my way of trying to "break the ice"

i don't really understand the problem, i can't make a picture of what they are expressing, if you could show me a pictue of the problem, i think ill be able to solve it

the reason I ask, is because I've got an exam over some general physics, and this is a example problem the teacher gave me, and i didnt know where to start


thanks
 
Draw an xy coordinate system.
Label the origin as O.
Mark a point F, so that:
- the line OF is at an angle of 30° WRT the x-axis.
- the distance OF is 20.
Mark another point R, so that
- the line OR is at an angle of 45° WRT the x-axis.
- the distance OR is 50.
BTW, it's convention to have angles counter-clockwise.

They want you to find the point G, so that OFRG is a parallelogram. They want to know the angle of the line OG WRT the x-axis.

OK?
 
thanks a lot, very helpful
