Conservation of Angular Momentum
A student stands on a frictionless platform that is free to rotate, holding a spinning bicycle wheel with its axis horizontal. The student then tilts the wheel so its axis is vertical. Which statement correctly describes the angular momentum of a particular system during this process?
A
The angular momentum of just the platform is conserved
B
The angular momentum of the student-platform system is conserved
C
The angular momentum of just the wheel is conserved
D
The angular momentum of the student-platform-wheel system is conserved
