Homework Statement
Imagine that a circular disc is rotating with a frictionless ball on it( ball is not at center of the disc) If we observe the motion of the ball from the rotating frame of reference, then how can we describe its motion?
Homework Equations
The Attempt at a Solution
As the motion of the ball is being observed from the rotating frame of reference, a centrifugal force must act on it but i know that it will appear as if the ball is moving in a circular path with its center at the center of the disc. If the net force on the ball is towards outside(centrifugal force), then how can it rotate because it has no inward acting fictitious centripetal force.. Please help...
