Okay, so our delivery truck is going 28 blocks to the north, then 16 blocks to the east, but then we're going 26 blocks to the south.
00:18
We want to know the total displacement.
00:21
It means it started here and ended up here.
00:26
What's this displacement? well, we created a right triangle, right? we've gone some distance in the north -south direction and some distance in the east -west direction.
00:35
So how do we figure that out? well, the easiest thing is that we can take a look at the 28 and the 26, right? if we went 28 blocks north and then 26 blocks south, north and then south, that really is just net two blocks north.
00:58
And we still have the 16 blocks east.
01:02
So what does that look like? two blocks north, 16 blocks east.
01:08
It's going from this point to this point...
