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. Block A is replaced with a block of mass 3M. The blocks are again released from rest. How much bigger (or smaller) is the new accleration?
3/5 as big (5/3 times smaller)
