Hello, here a block which is in the middle, sits on the table, and the coefficient of kinetic friction, muay, is 0 .330.
00:16
The block, the crate, has a mass of, let's call it, m2, which is 1 .83 kilograms.
00:30
Hanging block on the right, m3 is 3 kilograms.
00:33
And the one on the left m1 is 0 .590 kilograms.
00:41
Here you have to determine acceleration.
00:45
To find acceleration, we have to sketch the forces acting on each block.
00:49
Let's start with the one on the left.
00:55
It accelerates upwards.
00:58
Meanwhile, a block on the table experiences kinetic friction, tension t1 and t2 to the right.
01:11
Now let's show the forces acting on the 3 kilogram block.
01:22
So now let's write down second newton's low for each of these blocks...
