In the arrangement shown in Fig, a wedge of mass m₃ = 3.45 kg is placed on a smooth horizontal surface. A small and light pulley is connected on its top edge, as shown. A light, flexible thread passes over the pulley. Two blocks having mass m₁ = 1. 3 kg and m₂= 1.5 kg are connected at the ends of the thread. m1 is on smooth horizontal surface and m₂ rests on inclined surface of the wedge.    
Base length of wedge is 2 m and inclination is 37°. m₂ is initially near the top edge of the wedge. If the whole system is released from rest. Calculate:
