Okay, so for the data analysis, number one is to draw the free body diagram and write the summit of the forces of creation.
00:09
Suppose this is the rump and this is the angle theta and this is the object.
00:20
Suppose this is the center of mass of the object, pulling it vertically downwards is its weight to fg.
00:28
No gravitational to the surface of the rump is d.
00:35
Normal force and opposite the normal force.
00:43
So by geometry this is also angle theta is the component of weight in this direction.
00:51
As such, by trigonometry, it is fg plusin theta.
00:58
Then you can see that this force is fg sine theta and opposite of that is the static function force.
01:11
Now, let's denote this playing as y while this minus x.
01:24
Then the net force on the y plane is this.
01:33
And for the x plane was this...
