An Atwood's machine consists of two blocks connected by a light string that passes over a set of ideal pulleys, as shown above. Blocks A and B have masses 1/2 M and M , respectively. The blocks are released from rest and block B moves downward with an acceleration of magnitude a . Next, 1/4 M a block of mass is attached to block A , and the system is again released from rest. Which of the following gives the change inacceleration of block B ? 7.ABMMass =2Mass = MAn Atwood's machine consists of two blocks connected by a light string that passes over a set of idealpulleys, as shown above. Blocks A and B have masses M and M , respectively. The blocks are releasedfrom rest and block B moves downward with an acceleration of magnitude a. Next, a block of mass -M isattached to block A, and the system is again released from rest. Which of the following gives the change inacceleration of block B ?

Initially, when the masses attached to the Atwood machine are M and M/2. Therefore, the acceleration…
