Three masses are hung over two pulleys, as shown in Fig. 5.58. The pulleys are massless and frictionless. As- sume that my > (m + m3) and m > m3. (a) Show that the tension in the rope supporting the fixed pulley is T 16mmm38 m(m + m3) + 4m2m3 (b) Identify the mass that has the following acceleration: a = [m(m + m3) - 4mm3lg m(m + m3) + 4m2m3 m] m2 FIGURE 5.58 m3
