Solution of the D2 B15. Drum 200kg and a radius of 80 cm is rotated from the rest of constant force F1 = 30 N is applied tangentially to its rim. This creates a resistance force proportional to the angular velocity F2 = 15w, H, applied at a distance r = 45 cm from the axis of rotation. The drum is considered uniform cylinder. To determine the angular velocity of the drum 15 seconds after the start of the rotation.
