Thinkabout 35.6 - Jill and her MGR + Jill merry-go-round disk The Torque and Angular Momentum Model Sheet maybe helpful for this Thinkabout Phenomenon: Jill is atop a stationary merry-go-round, which is shaped like a disk and is free to spin around a vertical, frictionless axis. Jill is herself initially stationary. Big Question: If Jill begins to walk in the counterclockwise direction on the surface of the merry-go-round, what will the merry-go-round do? A. Use an appropriate diagram (energy-interaction, momentum, or angular momentum) to explain what will happen B. Create a vector equation and use column vectors to develop an algebraic expression that expresses your answer C. Use what you know about rotational inertia and predict the relative angular speeds of Jill and the merry-go-round (come up with an expression relating the two). Which one will rotate faster? Why? D. Finally, how is "Jill on the merry-go-round" like "Victoria on the boat"
