Blocks A and B have masses M and 2M, respectively. The blocks are connected using a light string and an ideal pulley in the Atwood machine shown. When the blocks are released from rest, block B accelerates downward with acceleration a. Block B is replaced with a block that has twice the mass. The blocks are again released from rest. Which of
the following is a correct expression for the new acceleration of the blocks?
