Problem 5.89

Three objects with masses m1 5.0 kg, m2 10 kg, and m3 15 kg, respectively, are attached by strings over frictionless pulleys as indicated in Figure P5.32. The horizontal surface exerts a force of friction of 30 N on m2. If the system is released from rest, use energy concepts to nd the speed of m3 after it moves down 4.0 m.
