Finding a resultant of several vectors is no more than adding the vectors up.
00:09
So here we have three vectors, p, q, and u, and we simply add all of those to get the resultant.
00:19
Furthermore, we are told that u is 4q.
00:23
So a reminder that as long as you are adding and subtracting, vectors can just be treated like algebraic symbols.
00:33
So our resultant in this case is p plus 5q.
00:40
And at this point, it's as simple as we can make it without including the actual components.
00:48
So we want to take 5q, and let's see, that just simply takes the scalar 5 and multiplies each of the separate components.
01:02
So remember that a scalar just scales the vector.
01:07
Makes it a little bit longer.
01:10
And we're just going to add p to that...
