So we're shown a figure in which we have a couple of different forces acting.
00:05
Let me actually draw that a little bit.
00:08
So the first case, we have one force is to the left, and the other one is down in that case.
00:18
And in the second case, we have one forces up, and one is at 120 degrees from there.
00:30
So let's see here.
00:32
We have, so let's see, we have this is f1 and this is f2, and this is f1, and this is f1, no, 2, and f1.
00:50
So in the first case, i called the resultant f -a, so the resultant is obviously going to be down here somewhere.
00:58
So we have f -a, the resultant force here, is, is, um, just this, which is minus 10 .2 in the x direction, and then this one is minus 16 in the y direction.
01:16
So then they ask us if we had a particle here or a body there, and it had a mass of 27 kilograms, which, what would the acceleration be? and what we need to do is divide this by 27 kilograms, and that minds it being minus 0 .378 in the x direction and minus 0 .593 in the y direction.
01:37
Acceleration is in the exact same direction as the net force.
01:43
And again, this is the vector.
01:44
We can get it in terms of magnitude and direction too...
