Well guys, in this problem, we have two identical block, each of mass, 2kg, rest on a frictionless surface.
00:17
For the block at the bottom, on the surfaces, the coefficient of static friction is zero.
00:26
The coefficient of static friction between the two blocks is 0 .3 .5.
00:31
We have to find out.
00:32
The maximum force exerted on the lower block so that the two blocks move together.
00:38
Now assume these two block as a system.
00:43
If these two blocks are a system, then we have their common acceleration.
00:49
You can write the force equals the mass of the system, that is 2m times its acceleration.

Okay, say this has equation one...
