I've just been wondering about this kind of problem. Let m be the mass of the smaller ball, and M be the mass of the larger ball. Assuming the ball does not slip and that the surfaces are frictionless, what is the time that it takes for the smaller ball to reach the bottom/floor if the the radii for the small and large ball are 2m and 10m respectively?
What does it become when there is friction with a coeffecient of 0.2?
