A force of P = 20 N is applied to the cable, which causes the 245-kg reel to turn without slipping on the two rollers A and B of the dispenser. Neglect the mass of the cable. Each roller can be considered as an 18-kg cylinder, having a radius of 0.1 m. The radius of gyration of the reel about its center axis is kg = 0.42 m. (Figure 1) Figuro Determine the angular velocity of the reel, measured counterclockwise, after it has made two revolutions starting from rest. Express your answer using three significant figures. Enter positive value if the angular velocity is counterclockwise and negative value if the angular velocity is clockwise.
