How can I find the net force of this ? (image included)

Click For Summary
To find the net force and direction of two arrows with the same angles, it's essential to know the angle between the vectors, which is specified as 45 degrees. Users are encouraged to show their work and calculations to receive more targeted assistance. Posting in the appropriate homework section with a completed template is recommended for better guidance. Providing additional context or examples can help clarify the problem. Understanding vector addition and the role of angles is crucial for solving such physics problems effectively.

you need to know some additional info: the angle between the vectors.

and given that you need to show some work before we can help you.
 
It's just an example for me to understand something, but I didn't know that it missed some additional info sorry, lol.
Let's suppose that the angle is 45 degree.
 
Please post this in the appropriate homework section, fill out the template and show what you have done yourself to solve the problem.
 

Thread 'Reference frames, center of rotation, etc'

Topic about reference frames, center of rotation, postion of origin etc Comoving ref. frame is frame that is attached to moving object, does that mean, in that frame translation and rotation of object is zero, because origin and axes(x,y,z) are fixed to object? Is it same if you place origin of frame at object center of mass or at object tail? What type of comoving frame exist? What is lab frame? If we talk about center of rotation do we always need to specified from what frame we observe?
