Task id16814

A flywheel with a moment of inertia of 0.86 kg m2 and a cylinder with a radius of 5 cm, the mass of which can be neglected, sit on a common shaft (Fig. 14.16). A thread is wound around a cylinder, from which a weight of mass 6.0 kg is suspended. How long will it take for the weight to drop 1 m? What will be its final speed? The initial speed is assumed to be zero.
