A pulley with a radius of 20 cm and a mass of 200 g is mounted on a common axis with a flywheel of the same radius and a mass of 500 g. A cord is wound on the pulley, to the end of which a weight of 1 kg is suspended. How far should the load go down in order for the flywheel with a pulley to acquire an angular speed of 6.28 rad / s? A flywheel and a pulley should be considered a uniform disc and ring, respectively.
