In this cushion it is told that the road which connects the balls a and b is clamped at the center in such a way that it can freely rotate.
00:11
Now a particle of mass m is dropped from a height on the ball b and sticks to it.
00:18
So first of all i am drawing the diagram for this given cushion.
00:22
This is the road and two particles that is b and a is connected with this road whose masses is given to us that is m.
00:32
And it is told that a particle of mass m, this particle p whose mass m is dropped from a height that is h.
00:41
And after it collision, it sticks to it.
00:44
So it becomes like after collision, its condition is this is p particle, this is b particle and this is our a particle.
00:58
This is the condition after collision.
01:01
Now in the first part, we have to find the angular momentum and angular speed of the system just tougher after the collision.
01:10
So let the particle p collides with the ball with a speed u and the system moves with the speed v just after collision...
