A solid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. (The cylindrical shell has light-weight spokes connecting the shell to the axle. A rope is wrapped around each cylinder and tied to a block. The blocks have the same mass and are held the same height above the ground, as shown in the figure (Figure 1) Both blocks are released simultaneously. The ropes do not slip. A) Which block hits the ground first? Or is it a tie? Explain. B) Complete the sentences with following terms.(solid) (hollow) , (translational kinetic) (gravitational potential) (rotational potential) (rotational kinetic) By the time the blocks reach the ground, they have transformed identical amounts of energy into energy of the cylinders. energy of the blocks and But the moment of inertia of a cylinder is higher than that of a cylinder of the same mass, so more of the energy of the system is in the form of rotational kinetic energy for the cylinder than for the one. This leaves less energy in the form of translational kinetic energy for the cylinder. But it is the energy that determines the speed of the block. So the block moves more slowly for the system with the cylinder, and so its block reaches the ground last.
