By means of a rope whose mass is negligible, two blocks are suspended over a pulley, as the drawing shows, with m1 = 12.2 kg and m2 = 43.4 kg. The pulley can be treated as a uniform, solid, cylindrical disk. The downward acceleration of the 43.4 kg block is observed to be exactly one-half the acceleration due to gravity. Noting that the tension in the rope is not the same on each side of the pulley, find the mass of the pulley.

Anybody have any idea how to do this?
I would appreciate any help.
Thank You.
