A ring (2 kg, r = 1 m) rotates in a CW direction with initial
angular velocity 10 s-1. A disk (4 kg, r = 1 m) rotates
in a CCW direction with initial angular velocity 40 s-1.
The ring and disk "collide" and eventually rotate together. Assume
that positive angular momentum and angular velocity values
correspond to rotation in the CCW direction.
What is the initial angular momentum Li of the
ring+disk system?
kg m2 s-1
What is the final angular velocity ωf of the
ring+disk system?
