High students in this question, three children are being given and we need to find out the value of acceleration a as well as direction of force which is taken as theta.
00:10
Now from the figure it is clear that the magnitude of force f1 is taken as 10 newton which is making a particular angle theta 1 to be equal to 45 degree with respect to the horizontal.
00:22
On the other hand magnitude of force f2 is taken as 8 newton which is making a particular angle theta 2 to be equal to 45 degree with respect to the horizontal.
00:30
To be equal to 30 degree with respect to the horizontal.
00:34
And here it is given that the frictional force f is taken to be 7 .5 newton.
00:40
On the other hand, the mass of the slad is taken as molator m to be equal to 6 kilogram.
00:46
Now from the figure, it is clear that this force f1 can be resolved into two components which are taken as f1 course theta 1 as well as f1 sine theta 1.
00:59
On the other hand, force f2 can be resolved into two components which are taken as f2 into cose theta 2 as well as f2 into sine theta 2.
01:10
And here we can say that the value of f1 into cose theta 1 will be equal to 10 into coarse value of 45 degree.
01:20
On the hand, f1 into sine theta 1 will be equal to 10 into sine value of 45 degree.
01:29
Similarly, we can say that the value of f2 into cos theta 2 will be equal to 8 into cos 30 degree.
01:38
On the other hand, f2 into sine theta 2 will be equal to 8 into sine value of 30 degree...
