QUESTION 2 The System shown in Figure consists of a light, inextensible cord. light, frictionless pulleys, and blocks of equal mass. Notice that block B is attached to one of the pulleys. The system is initially held at rest so that the blocks are at the same height above the ground. The blocks are then released. Find the speed of block A at the moment the vertical separation of the blocks is h=8.29m. Submit your answer in ms using 3 signicant gures.
