A ring of mass 2 M and radius 1 R rotates in a CCW direction
with initial angular speed 2 ω. A disk of mass 4 M and radius 1 R
rotates in a CW direction with initial angular speed 4 ω. 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 are the moments of inertia for the ring and disk? Write your
answer in terms of MR2.
Iring = M R2
Idisk = M R2
Remember that I = beta*MR2. |
