Homework Help Overview

The discussion revolves around a physics problem involving two forces, F_1 and F_2, acting at a point with specified magnitudes and angles. The participants are tasked with finding the x and y components of the resultant force, as well as its magnitude.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the need to resolve the forces into their x and y components and question how to properly perform this step. There is mention of confusion regarding the addition of forces and the calculation of the resultant force's magnitude.

Discussion Status

Some participants express uncertainty about their approaches and seek clarification on how to separate the forces into components. A link to a resource is provided, suggesting an attempt to guide understanding without offering direct solutions.

Contextual Notes

Participants note difficulties in understanding the vector addition process and the implications of the angles provided in the problem. There is an indication of prior attempts that may not have yielded correct results, leading to further exploration of the problem.

Homework Statement


Two forces, F_1 and F_2, act at a point. F_1 has a magnitude of 9.60 N and is directed at an angle of 61.0 degrees above the negative x-axis in the second quadrant. F_2_vec has a magnitude of 7.00 N and is directed at an angle of 53.7 degrees below the negative x-axis in the third quadrant.

1.) What is the x component F(x) of the resultant force?

2.) What is the y component F(y) of the resultant force?

3.) What is the magnitude F of the resultant force?

I have tried different methods but i think my approach is all wrong(mult. the degrees by the N) . does anyone know how to solve it?

This is a vector addition problem.

Resolve the vector into its x,y components and add to find the Resultant vector components. Then just transfer the answers.

\vec{F_1} + \vec{F_2} = \vec{F_{Result}}
 
sorry but as i said before i have no clue as to how to solve this problem i added the two forces to find part 3 but i got 16.6 which turned out to be wrong. I have a problem in seperating the forces into an x and y component. How exactly do you go about doing that when you are given a problem like this?

OK. Here you go. This should be helpful:
