Q11. As shown in the image below, the 33-kg block A and the 44-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 1.1 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 B

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. Each step is of uniform height d. The mass of each object is a multiple of the base mass m: object1 has mass 4.00m, object 2 has mass 1.96m, and object 3 has mass m. When the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. If the objects are then relocated as shown, what is the new total potential energy of the system? Each answer requires the numerical coefficient to an 2 algebraic expression. Each algebraic expression is given using some combination of the variables m, g, and d, where g is the acceleration due to gravity. Enter only the numerical coefficient. (Example: If the answer is 1.23mgd, just enter 1.23)
