Astring is wrapped around a uniform cylinder of mass m and radius r. the cylinder is released from rest with the string vertical and its top end tied to a fixed bar. a uniform disk, cylindrical in shape, of mass m and radius r is suspended from a string. the top end of the string is attached to a fixed bar. the string extends down through a distance h before reaching the disk, whereupon the string winds around the cylindrical body of the disk. (a) show that the tension in the string is one-third the weight of the cylinder. (submit a file with a maximum size of 1 mb.) (b) show that the magnitude of the acceleration of the center of gravity is 2g/3. (submit a file with a maximum size of 1 mb.) (c) show that the speed of the center of gravity is 4gh 3 1/2 after the cylinder has descended through distance h. verify your answer to (c) with the energy approach.
