Problem 125CP

Double Atwood’s Machine.? In ?Fig. P5.114? masses m1 and m2 are connected by a light string A over a light, frictionless pulley B. The axle of pulley B is connected by a light string C over a light, frictionless pulley D to a mass m3. Pulley D is suspended from the ceiling by an attachment to its axle. The system is released from rest. In terms of m1, m2, m3, and g , what are (a) the acceleration of block m3; (b) the acceleration of pulley B ; (c) the acceleration of block m1; (d) the acceleration of block m2; (e) the tension in string A; (f) the tension in string C? (g) What do your expressions give for the special case of m1 = m2 and m3 = m1 + m2? Is this reasonable?
