Bar mass m, located on the inclined plane is retained therein by friction. To determine the time in which the bar will come down on an inclined plane at a distance of 0.98 m, if it will move with an acceleration of 0.98 m / s² in the horizontal direction. The angle of inclination of the plane of the horizon 30. The coefficient of friction between the bar and the plane 0.6. In solving the problem use the frame of reference associated with the ramp.
