Two blocks A and B, of mass 5 kg and 6kg respectively, are connected by a cord which passes over pulleys as shown. A collar C, of mass 4kg, is placed on block and the system is released from rest. After the blocks have moved through 0.9m, collar C is removed and the blocks continue to move. Determine the velocity of block A just before it strikes the ground.
Numbers in FIG. P13.26 from top to bottom are: 0.3m, 0.6m, and 1.5m.
Letters in FIG. P13.26 from top to bottom are: C, A, and B.
