Hello, Can you help by providing some answers to a Roulette problem I have. The problem is that a roulette ball spins in the grove of a cone until the power pulling it down exceeds the force created by the push of the spin of the ball. Also, the diameter of the ball exceeds the thickness of the grove. If the above is true, then does a relationship exist between where the ball leaves the grove, which is dependent on the force put into the spin as well as the starting point of the spin and a certain co-ordinate on the cone that the ball will cross as it rotates downwards? Any help will be much appreciated.
