The Figure Shows a System Consisting of Three Blocks,a Light

question 101

Short Answer

The figure shows a system consisting of three blocks,a light frictionless pulley,and light connecting ropes that act horizontally on the upper two blocks.The 9.0-kg block is on a perfectly smooth horizontal table.The surfaces of the 12-kg block are rough,with µ_k = 0.30 between the 12-kg and 9.0-kg blocks.The mass M of the hanging block is set so that it descends at a constant velocity of 3.25 m/s.
(a)What is the mass M of the hanging block?
(b)The mass M is now changed to 5.0 kg,causing it to accelerate downward after it is released.What is the acceleration of the hanging block?
