A uniform, solid cylinder with mass M and radius 2.1 rests on a horizontal tabletop. A string is attached by a yoke to a frictionless axle through the center of the cylinder so that the cylinder can rotate about they axle. The string runs over a disk-shaped pulley with mass M and radius R that is mounted on a frictionless axle through its center. A block of mass M is suspended from the free end of the string (the figure (Figure 1)). The string doesn't slip over the pulley surface, and the mulindor rolle without clinging on tha tobloton Figure 1 of 1 ) M 2R R M Provid MPart A What are the kinetic energies of the 3 bodies when the hanging block has fallen a distance h?
