Question

A student sitting at rest on a chair that is free to rotate holds a spinning bicycle wheel that rotates in the horizontal plane, shown in a). When the student flips the bicycle wheel over, as shown in b), he will

Answer 1

Applying Conservation of Angular Momentum,

Initial Angular Momentum = Final Angular Momentum

Now since, Angular Momentum direction is reversed due to change spinning direction of wheel, Student will start spinning in opposite direction to the flipped bicycle wheel, to maintain the Angular momentum

ans: spin in the opposite direction as the flipped bicycle wheel
