Conservation of Angular Momentum
Two identical disks, each with a moment of inertia I, are initially rotating with angular velocities ω₁ and ω₂ in opposite directions. The disks are brought into contact and eventually rotate with a common final angular velocity. What is the magnitude of the change in the total angular momentum of the system?
A
2I|ω₁ - ω₂|
B
I|ω₁ - ω₂|
C
0
D
I|ω₁ + ω₂|
