Using g$=10$

Block A weighs $1\mathrm{.}0$ N and block B weighs $4\mathrm{.}0$ N$.$ The coefficient of kinetic friction between all flat surfaces is $0\mathrm{.}10.$ Box A sits on top of Box B and Box A is connected to another box that hangs off the table in the system shown. Assume massless string and frictionless pulleys

Draw a force diagram then

find the unknown mass, such that the system moves with an acceleration of $2\mathrm{.}0$ m$/$s$^2$
