PRZ M 3. A block of mass ml= 6kg on a rough, horizontal surface is connected to a ball of mass m2=1.5kg by a lightweight cord over a lightweight, frictionless pulley, as shown. A force of magnitude F= 40N at an angle of 60° with the horizontal is applied to the block as shown. The coefficient of kinetic μk = 0.36 friction between the block and surface is Determine the magnitude of the acceleration of the two objects. 4. In a nou Vng Fsin 0 F cos 0
