## Homework Statement

Three blocks A, B, and C of masses m1, m2 and m3 respectively are lying on top of each other on a frictionless table with A on top and C on bottom. The coefficient of friction between A and B is u1 and between B and C in u2. Find the accelerations a1, a2 and a3 of the three blocks if a horizontal force F is applied on:

(a) A, (b) B and (c) C

The force F is applied on one block at a time and the accelerations are noted and then it is applied on the second one then the third one giving us three sets of accelerations.
