Hi there.
00:01
So for this problem, we are told to draw a free body diagram for the figure that is shown below.
00:10
So this is the figure that we are given in here.
00:14
So as you can see, it is an inclined plane and on top of it we have an object with a mass m.
00:25
So what we need to do is to draw the free body diagram and and so i'm going to start with the object.
00:34
Of course, we're going to draw this object incline as it is in the figure.
00:41
So we can draw the a axis along this.
00:49
So this is the x -axis and this in here is the y -axis.
00:58
So in this case, because we are not given the information about frictional force, we are going to assume that there are going to be two forces that are opting on this object of mass m and those forces are the weight the gravitational force and the normal force first we know that the normal force is always perpendicular to the surface so in this case and it's going to be along the y axis so this is the normal force now since the object is in line, we know that the weight always points towards the center of the earth.
01:40
So that is always doubt.
01:43
So it's going to be in this direction.
01:46
This is the weight.
01:48
And we know that the weight is defined as the mass of the object times the acceleration due to gravity...
