Task id10310
A homogeneous rod 8 cm long slides along a smooth horizontal surface parallel to its length and hits the boundary separating the smooth surface from the rough one, the coefficient of friction about which is 0.2. The boundary line is located perpendicular to the speed of the rod. Find the initial speed (in cm/s) of the rod if it stopped at the moment when it half crossed the boundary. g = 10 m/s2.
