APFIVE Conservation of Angular Momentum
A student, initially at rest on a stool that can rotate freely, holds a spinning bicycle wheel with its axis horizontal. The student then flips the wheel, reversing its direction of spin. What is the subsequent motion of the student-stool system?
A
The system remains stationary with zero net angular momentum
B
The wheel’s angular momentum increases to compensate
C
The stool rotates to conserve the system’s angular momentum
D
The wheel stops spinning due to angular momentum transfer
