Exploration 11.5: Conservation of Angular Momentum
Please wait for the animation to completely load.
A man is standing beside a 150-kg merry-go-round and suddenly drops a red object onto the merry-go-round (position is given in meters and time is given in seconds). You may change the mass of the object dropped on the merry-go-round and assume that the merry-go-round is a solid, uniform disk. Restart.
- What happens to the final angular velocity of the merry-go-round when a heavier object is dropped onto it?
- Is there a mass that you can add to make the final angular velocity exactly half of the initial angular velocity? If so, what is it?
- How do your answers to (a) and (b) relate to the conservation of angular momentum?
