Hi, so in this question we are given this cylinder c and it is being pulled out pulled up by using this rope and a pulley system.
00:11
Here it says that on this system we have this point a.
00:16
This point a is being drawn towards this drum.
00:20
So this is our drum and it is being drawn towards the drum with the velocity.
00:25
We call it as va and the velocity with which it is being drawn.
00:30
Is 6 meters per second.
00:33
So we have to find out the speed of the cylinder by which it is being lifted up.
00:40
So find the velocity of cylinder.
00:47
So we denoted by vc and it will be we are saying this is upwards.
00:54
So here in this diagram what we have is that if at this point a in the string we have we have a tension t.
01:05
Let us say that the tension here is t.
01:07
So this string is also going in this direction...
