By means of a rope whose mass is negligible, two blocks aresuspended over a pulley.One block wighs 11.0-kg and the other blockweighs 44.0-kg. The pulley can be treated as a uniform solidcylindrical disk. The downward acceleration of the 44.0-kg block isobserved to be exactly one-half the acceleration due to gravity.Noting the tension in the rope is not the same on each side of thepulley, find the mass of the pulley.
