An Atwood's machine consists of two masses, mA and mB, which are connected by a massless inelastic cord that passes over a pulley, see the figure(Figure 1) .
Part A
If the pulley has radius R and moment of inertia I about its axle, determine the acceleration of the masses mA and mB. [Hint: The tensions FTA and FTBare not equal. We discussed the Atwood machine in Example 4-13 in the textbook, assuming I=0 for the pulley.]
