1. The problem statement, all variables and given/known data
I have been facing constant problems in solving questions about friction. I wish to formulate a general method of solving such questions.

Here u1, u2 and u3 are friction coefficients. (Assume kinetic coefficient to be same as limiting static coefficient )
I wish to find the acceleration in each block in a systematic manner when a force F is applied on block
1) A
2) B
3) C

Help me discern a solution in a systematic manner in order that I may remember it for a long time.

Re: Friction:

1)Proceeding for the first part. A force F newton is applied on block A. My aim is to calculate the acceleration of all the 3 blocks. How shall I proceed?
