1. The problem statement, all variables and given/known data A small solid sphere, with radius 0.25 cm and mass 0.61 g rolls without slipping on the inside of a large fixed hemisphere with radius 17 cm and a vertical axis of symmetry. The sphere starts at the top from rest. And I figured out that the KE at the bottom is = .001J 2. Relevant equations I really don't know what equations would be relevant besides a proportion.. 3. The attempt at a solution I'm thinking it's something like (#/.001) = (x/100) and I cross multiply to find x but I really have no clue and would really appreciate some help on this one!
