"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

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

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.

i dont really understand the problem, i cant 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

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?
