A flat washer of mass M lies on a thin plate at a distance L from its edge (figure). The plate is pulled out from under the washer at a high constant speed, which practically does not have time to move. Find the dependence x(t) of the distance traveled by the puck on the time of its sliding along the table surface. How far will the puck eventually move? Assume that the friction force between the puck and the board, the puck and the table is directly proportional to the speed with a coefficient of proportionality g.
