Q11. As shown in the image below, the 39-kg block A and the 43-kg block B connected by the weightless, frictionless pulley system are released from rest. If initially the total combined potential energy of blocks A and B is 0, what is their combined potential energy when block A has displaced downwards by 0.6 m? Negative sign must be included if the energy is negative. Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point, and include proper SI unit. Take g = 9.81 m/s². A Your Answer: Answer OF B units
