A block of mass m2 on a rough, horizontal surface is connected to a ball of mass m1 by a lightweight cord over a lightweight, frictionless pulley as shown in the figure. A force of magnitude F at an angle ?θ with the horizontal is applied to the block as shown, and the block slides to the right. The coefficient of kinetic friction between the block and surface is ??μk. Determine the magnitude of the acceleration of the two objects.
