4. A6 kg object placed on a frictionless, horizontal table is connected toa string that passes over a pulley and then is fastened to a hanging 10 kg object, as shown in figure. Draw free-body diagrams of both objects. Find the acceleration of the two objects, the tension in the string, and the normal reaction force acting on me. m, my 5 5. An object of mass m= 30 kg is placed on a rough surface indined by an angle 0 = 45 relative to the horizontal, as shown in figure. Find the acceleration of the object given that the coefficient of kinetic friction u= 0.27.
