The weight is used to turn the gear system shown below. Gear A has a mass of 15 kg and a radius of gyration of 100 mm about its center of mass. Gear B and Drum C have a combined mass of 25 kg and a radius of gyration about their mass center of 165 mm. If the system starts from rest, determine the speed of the 55-kg weight after it has been lowered 3 m, the angular velocity of each gear, and the linear velocity of the meshing teeth between Gear A and Gear B. 100 mm 150 mm 0.0 B 200 mm D
