To solve this problem, first time just writing the given data here.
00:04
Coefficient of friction is given by mu is equal to 0 .10.
00:10
The value of angle theta is given as 30 degree.
00:14
Now i can draw a rough diagram of the given situation as this.
00:18
This is the rough diagram.
00:20
This angle is theta and theta is equal to 30 degree.
00:24
And here i can show the forces as just look at it carefully.
00:29
Waiting in this direction mg and here mg cost theta is working in this direction and in this direction mg sine theta is working now i can write the value of fy is equal to mg cost theta here and the value of fn is equal to mg cost theta frictional force is given by fn which is equal to, sorry, ff is the value of frictional force which is equal to mu multiplication fn, which is equal to 0 .10 multiplication m g cost theta.
01:16
Also the value of fnett is equal to m g sine theta minus f f f f f.
01:25
So here the value of f net is equal to mg sine theta minus point f f f f f f f.
01:32
0 .10 multiplication m g cost theta...
