AP Physics I Homework - Angular Momentum 3. A group of physics students are on a playground and wish to use the merry-go-round shown in an experiment to test the Law of Conservation of Angular Momentum. The merry-go-round can freely spin about its axis in the center and has almost no friction. The students bring with them the following equipment: A bathroom scale that can measure the mass of a person A spring scale that can measure up to 100 N of force. . A meterstick, stopwatch, and several meters of light rope. (a) The students first need to measure the rotational inertia Imgr of the merry-go-round. They wrap several turns of the rope around the outer radius of the merry-go-round. In the space below, outline a procedure the students should follow to make measurements necessary to calculate the rotational inertia of the merry-go-round. Explain how the measurements will be used to calculate the rotational inertia of the merry-go-round
