A 2.0 kg block is placed on top of a 3.0 kg block, which lies on a frictionless surface. The coefficient of kinetic friction between the two blocks is 0.30; they are connected via a pulley and a string. A hanging block of mass 10 kg is connected to the 3.0 kg block via another pulley and string. Both strings have negligible mass and both pulleys are frictionless and have negligible mass. When the assembly is released, what are (a) the acceleration magnitude of the blocks, (b) the tension in string 1, and (c) the tension in string 2?

isn’t there supposed to be the normal force from the block above being applied to the block below?

Thank you so much. You have no idea how much this helped!

why is it that initially we do not consider the fact that the bottom block of the two stacked blocks will have the mass of block 1 and 2. what i wrote is T2-T1-fk=(M+m)a.. why is that not the case here? is it because they are being pulled in opposite directions and not the same direction?
