1. The problem statement, all variables and given/known data[/b I have 2 question 2. Relevant equations which one gets to point o earlier?we release them,both of them have the same conditions. the distance and mass every thing are the same. I have attached the figures 3. The attempt at a solution I think in the first one because of the rotational motion that ball has ,the energy of it is divided, so ball get later, Second one: In one figure on the way there is a hole and another one there isn't, I don't have any idea that which one get faster!
