A solid homogeneous eylinder rolls without slipping on the horizontal plane. The cylinder has a mass of $90$ kg and is at rest in the position shown. The stiffness of the spring is $450$ N$/$m$,$ and its unstretched length is $600$ mm$.$ What will be the angular speed of the cylinder when the spring has moved the center $500$ mm to the$$right$? 600$m
