We are given a velocity time graph.
00:03
And so i'm going to kind of roughly draw right here.
00:05
So it goes straight for a little bit, and then it just goes off.
00:08
But we're asked to find acceleration for the first four seconds, which will be our straight point.
00:13
And so i'll put some points right here.
00:15
This will be four.
00:16
This is point red.
00:19
And this is eight meters per second.
00:21
Four seconds and eight meters per second.
00:24
There's another point right here, which is at two seconds in four seconds.
00:31
Four meters per second, and there's also zero, zero.
00:34
And so anytime you have a graph in physics, you really need to look to see if you're finding area under the curve, which the two variables in our graph would be multiplied or slope...
