One end of a light inextensible string is attached to a ceiling. The string passes under a smooth light pulley carrying a weight C and then over a fixed smooth light pulley. To the free end of the string is attached a light scale pan in which two weights A and B are placed with A on top of B as shown. The portions of the string not in contact with the pulleys are vertical. Each of the weights A and B has a mass M and the weight C has a mass 5M. If the system is released from rest, then which of the following options is/are correct: (A) The acceleration of the movable pulley is (B) The tension in the string between p and pz is 30Mg/13 (C) The reaction force between the weights A and B is 15Mg/13 (D) The reaction force on the pulley p is 30Mg/13

The figure above shows three blocks, 1, 2, and 3, of mass m1, m2, and m3 respectively. Block 2 is sitting on top of block 1, and blocks 1 and 3 are attached by a string that is wrapped around two pulleys, as shown in the figure. The upper pulley is fixed in place, while the lower pulley moves with block 3. When the system is released from rest, block 3 accelerates downward and block 2 slips relative to block 1. The coefficient of kinetic friction between block 1 and the table and between blocks 1 and 2 has the value Ī¼. You may assume that the string is massless and inextensible and that the pulleys are massless and frictionless. The downward acceleration of gravity is g. Find an expression for the magnitude of the acceleration of block 3 in terms of some or all of the parameters m_1 for m1, m_2 for m2, m_3 for m3, mu for Ī¼, and g.
