So in this problem in the first sub part we have to find the free body diagram of the slide.
00:06
This will be the, suppose this is the incline.
00:11
I'm showing the slide with a small box, suppose it is a small box.
00:15
Then we have been told that this angle, this angle have been given as theta.
00:23
This will be 180 degree minus theta.
00:26
This is 90 degrees.
00:27
So this will be, this will be theta minus 90.
00:35
So the force of acting are normal force and the weight of the sled that is ws.
00:50
Now if you have to take components, if you have to take components, this will be the first component.
00:57
Let this be the x axis and this is the y axis.
01:07
So if you take components, this will be ws, ws sine theta minus 90...
