Two identical rollers are mounted with their axes parallel, in a horizontal plane, a distance 2d = 35. 1 cm apart. The two rollers are rotating inwardly at the top with the same angular speed ω. A long uniform board is laid across them in a direction perpendicular to their axes. The board of mass m = 3. 52 kg is originally placed so that its center of mass lies a distance x0 = 10 cm from the point midway between the rollers. The coefficient of friction between the board and rollers is µk = 0. 653. What is the period (s) of the motion? m 2d x0
