Please help. This problem involves finding the acceleration of masses attached to pulleys. Thank you. Q1. Not from book. For the pulley system shown below, determine the vertical accelerations ofthe two masses A and B, whose masses are, respectively, m1 and m2. The pulleys and ropes aremassless, frictionless and the roles are thin and inextensible. Given m, = 10 kg, m2 == 9.81 m/s?. Be clear in your notation whether downwards is positive or negative.10 kg, and gHint: In addition to FBD and "F = ma," you will need a relation between the accelerations of A andB due to their being connected. Recall "constrained motion" and we derived this exact relation inclass. Re-do the derivation here and use it.%3Dropezropel,A(m.)(ma)
