In this question, this is the situation.
00:06
Okay, so just draw better.
00:15
Okay, on the horizontal surface and then there's a wall.
00:19
There are two blocks, and the stack on top of each other.
00:24
And then the top one is attached to a string as attached to the wall.
00:28
So this is block a, and then this is not b.
00:31
Block b is being pulled to the left.
00:34
Okay.
00:34
With a force okay and so um then we are given that the uh coefficient of static fission is 0 .2 uh mass of block a is 4 pg ms of block b is 6kg right then in part there are two parts in this question in part a you want to draw the free body diagrams and mark out the action reaction pairs.
01:10
So for block a, using a dots, we have the weights force by earth on a, and then the normal force by b on a.
01:26
Okay, and then we have a tension to the left by the rope on a.
01:32
And then the friction from b on a okay then on block b...
