Resulting angular speed

  1. Apr 9, 2015 #1
    1. The problem statement, all variables and given/known data

    A circular turntable of mass 2.0 kg and radius 6.0 inches is rotating freely at 66 2/3 rpm. If a 500 gram blob of clay is dropped on the disk at a distance of 4.0 inches from the center, what is the resulting angular speed of the system? Treat the clay as a point mass (I = MR^2) and the turntable as a disk.

    2. Relevant equations


    3. The attempt at a solution
    I understand the resulting angular speed will be the sum of the two. But what does moment of inertia have to do with it??

    What do you mean about the angular speed being the sum of the two? Doesn't sound right.
    What relevant conservation law do you know?
