Three objects with masses m, = 5.00 kg, m, = 10.0 kg, and m3 = 15.0 kg, respectively, are attached by strings over fric- tionless pulleys as indicated in Figure P5.85. The horizontal surface exerts a force of friction of 30.0 N on mg. If the system is released from rest, use energy concepts to find the speed of mg after it moves down 4.00 m. т тg Figure P5.85
