Hi friends, here it is given.
00:06
Three blocks are in contact to each other.
00:15
Having the mass m1, m2, m3 on the horizontal surface, having kinetic friction point one.
00:24
Mass of the blocks are 4kg, 5 kg and 6 kg.
00:59
Force of 20 newton is applied on m1.
01:05
In the first part, we have to find the acceleration.
01:09
See the free body diagram.
01:12
Force between the surfaces of m1 and m2.
01:20
Say fab, force between the surfaces 2 and 3 will be.
01:30
Sorry, you can skip the name 1 and 2, 2 and 3.
01:37
Friction, f1, f2, f3.
01:45
Normal force, n1, n2, n3.
01:56
M1g, m2g, and...
