00:01
And so with the given graph, we want to calculate a, the distance traveled in 40 seconds.
00:07
So we just want to look at the graph and just calculate, look at the distance in each portion.
00:15
So in the red portion, we have a distance traveled of three meters.
00:24
And then in the blue, that distance travel is from three to six, so three meters.
00:38
And then in the purple, there's no distance travel there.
00:46
And then we have the green.
00:49
So even though the distance is going backwards, or a position is going backwards, they go from 6 down to negative 7.
00:59
So that's the distance of 13.
01:04
And then in the blue, they went from negative 7 up to 18.
01:13
So that's 25.
01:16
So the total distance traveled would be 6 plus 13 plus 25.
01:24
So that should be a total of 44 meters traveled.
01:31
So the displacement traveled in 40 seconds would only be just the final distance, which would be 18 meters.
01:49
For c, we went to velocity at 22 seconds...
