The mass of the sled and the passenger put together is observed to be 50 kg and the coefficient of kinetic friction between the surface and the sled is observed to be 0 .2.
00:13
Now, you are visualizing the situation.
00:16
Let's say this is the sled.
00:17
Her is the mass and total mass of the system is 50 kg.
00:23
The force is applied above the horizontal at an angle theta where theta is given to us as 25.
00:31
Degree.
00:32
Now let us resolve this force vector.
00:34
So if we are resolving this force vector, we get f cos theta horizontally and vertically upward.
00:41
We are going to get f sine theta.
00:46
And vertically upward due to the contact between the surface and the ground, there is going to be a normal reaction.
00:52
Vertically downward, there is going to be mg towards the left.
00:55
There is going to be friction...
