Rotation a Rolling Mastery Check Score: 0/4 0/4 answered Question 4 7.5 kg The pulley in the system shown made of two uniform disks that are glued together. The smaller disk has a mass of 0.95 kg and radius of 38 cm. The larger disk has a mass of 3 kg and radius of 76 cm. The pulley is mounted on a frictionless axle that runs through the center of the smaller disk and the midpoint between the center and edge of the larger disk. A rope is wrapped around the smaller disk such that it does not slip. Use work-energy principles to determine how far the hanging mass has fallen when the kinetic energy of the pulley is 250 J, if the system started at rest. d = m
