The ball is going to move in a circle, at a const speed.
So what is the angular velocity of the ball is related
to the angular velocity of the turntable?
The problem is:
A turntable rotates with const angular speed Omiga. A ball
rolls on it, without slipping. The moment of inertia of the
ball is (2/3)M(R^2), and the mass of the ball is sphereically
evenly distributed.
This is an undergrad phys competition problem, few student really
worked it o |
