A light rope is attached to a block with a mass of 6kg that rests on a horizontal, frictionless surface. The horizontal rope passes over a frictionless, massless pulley, and a block of mass m is suspended from the other end. When the blocks are released, the tension in the rope is 18N. (a) draw a free-body diagram for each block. (b) what is the acceleration of the 6-kg block? (c) what is the mass m of the hanging block?   (d) using the value of the hanging mass calculated in part c, what would be the acceleration and the tension in the rope if the coefficient of kinetic friction between the 6-kg mass and the horizontal is 0.10?
