A 4-kg block is connected by means of a massless rope to a 2-kg block in the figure. If the coeficient of sliding friction between the 4 kg mass and the table is 0.150, find the acceleration of the system, and the tention in the connecting cable.

    I assume the 2kg block is over a pulley, hanging downward.

    netforce=totalmass*a
    2*g=(6g)a solve for acceleration a.

    Tension=2(g-a)
