Задача id12657

A rope of length l=20 m is thrown over a block. At the initial moment, the rope hangs symmetrically and is at rest, and then, as a result of a slight push, it begins to move along the block. Will the motion of the rope be uniformly accelerated? What will be the speed of the rope when it leaves the block? Neglect the mass of the block and consider the radius of the block small.
