A particular Ferris wheel has a radius of 25 meters, and it makes one complete revolution around its axle (at location A) in 20 seconds. In all of the following questions, consider location A (at the center of the axle) as the location around which we will calculate the angular momentum. At the instant shown in the diagram, a child of mass 30 kg, sitting at location F, is traveling with velocity < 7.9, 0, 0> m/s.
