Question

Vectors u and v are shown on the graph.Which of the following vectors represents u + v?

Answer 1

Let's find which vector represents u+v

If you want to add two vectors you must put together the beginning of one with the end of the next one and then you have to draw the vector that connects the begging of the trajectory with the end of it, let's do it:

And therefore we can draw the vector in the plane, let's do it:
