Question

Two blocks A and B, of mass 6 kg and 10 kg, respectively, are connected by a cord which passes over pulleys as shown. A 9 kg collar C is placed on block A and the system is released from rest. After the blocks move 4.0 m, collar C is removed and blocks A and B continue to move.assuming coller and string passing through it is smooth, Determine (a)the speed of block A just after coller has been removed and (b)the speed of block B just before block A hits horizontal surface

Answer 1

Answer:

Two blocks A and B,. of mass 4 kg and 5 kg, respectively, are connected by a cord which passes over pulleys as shown. A 3-kg collar С is placed on block A and the system is released from rest. After the blocks have moved 0.9 m, collar С is removed and blocks A and В continue to move. Determine the speed of block A just before it strikes the ground.
