Hi guys, now in this column two blocks are attached to a massless cord and hung around a maxless frictionless pulley.
00:06
This is a diagram that i have.
00:09
Let me first draw the diagram and solve the problem.
00:13
So first i need to draw the diagram of this problem.
00:19
Now these are the pulley that we have and with this pulley two blocks are connected.
00:26
Let me first connect this pulley with this plank.
00:33
This is we have a first object.
00:35
Which we call it what m1 it looks a little bit big this one is looked like this let me connect this one like this and we have a second object which is there and this is what this one is look like this this is what actually it is not attached to what this one let me remove this part this mass of this one is that 9 kg and this one is 7 kg and this is 30 degree.
01:25
The surface is frictionless.
01:27
We need to find out acceleration.
01:29
Also we need to find out tension in the string.
01:33
If i draw the fbd, there is a 9g which is acting downward.
01:36
Tension will be act like this and let's say this moves with an acceleration of a.
01:42
Similarly for this one, let's say this moves with the acceleration of a.
01:47
Tension will be worked like this...
