A 4 kg block is stacked on top of a 12 kg block which is accelerating along a horizontal table at a=5.2 m/s^2. Let uk=us=u (friction). a) what minimum coefficient of friction u between teh trwo blocks will prevent the 4 kg block from sliding off? b) if u is only have this minimum value, what is the acceleration of the 4kg block with respect to the table? c) with respect to the 12kg block? d) what is the force that must be applied to the 12kg block in a) and b) assuming the table is frictionless?
