Homework Equations
My equations are
netforceyA = -MG + Friction between A and Hand + Friction between A and B
netforceyB = -MG + Friction between B and A
The Attempt at a Solution
Friction between A and B are equivelant due to Newtons third law since they are both accelerating upwards at the same rate correct?
I am not understanding this problem very much.. i know that the netforce = 0 for both cases since they are accelerating upwards at same rate (shown by velocity vector in middle of boxes) so the acceleration is 0. I don't know how to figure the rankings after solving the equations for the forces..
