Homework Equations
none? I apologize if I am overlooking any equation, but there are no equations that I know of that can help when adding vectors. Perhaps the Pythagorean theorem in some cases.
The Attempt at a Solution
I really don't understand how to add this type of vector. Generally with vectors I separate them into their horizontal and vertical components, but in this case there is no angle given really..so I think that would be impossible. (Sine/Cosine won't work without an angle!)
Thank you so much for your patience with me! I'm afraid I don't understand the concept very well...this is my first physics class, and my only knowledge of Physics is self-taught.
