More about the Puzzle of a Marble in a Spinning Pipe
Mungan, Carl E.
Physics Education, v50 n6 p722-726 Nov 2015
What trajectory in the laboratory frame does a marble follow if it is held inside a freely rotating pipe and then suddenly released so that it can slide frictionlessly outward along the pipe? A previously published solution is only valid for a pipe of small moment of inertia (so that it is either low in mass or short in length).
