Okay, we want to graphically determine the result of the following three vector displacements.
00:06
Before we do, let's draw some axes.
00:16
There's our x -axis, and then we'll just draw y -axis as well.
00:23
Okay, our first vector is 34 meters long, and it's at 25 degrees north of east.
00:32
Okay, so let's label these directions.
00:36
Let's move this a little bit.
00:38
There we go.
00:40
So north, east, south, and west.
00:49
Okay, now our first vector is 34 meters long at 25 degrees north of east.
00:58
So let's get out our ruler here.
01:03
We're going 10, 20, 34 meters.
01:10
Okay, and then we're now going 48 meters.
01:14
At 33 degrees east of north.
01:22
So we go due north and then we go 33 degrees east of that.
01:36
Okay, and we're going 48 meters.
02:01
Something like that.
02:04
Okay, and maybe let's throw the angles on here real quick.
02:10
So this is 25 degrees 34 meters.
02:18
This one's 48 meters and it's 33 degrees.
02:30
Okay, the last one we'll do green.
02:33
It's 22 meters long at 56 degrees west of south...
