Two blocks are pushed along a horizontal frictionless surface by a force of 20 newtons to the right. The force acts on the 3 kg block, which in turn pushes the 2kg block sitting next to it. The force that the 2-kilogram block exerts on the 3-kilogram block is......

    figure acceleartion first.

    a= 20/5= 4m/s^2

    So to make the 2kg block accelerate at 4m/s^2...
    F=ma, and of course that is the force between the 2,3 blocks
