Homework Statement
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
Homework Equations
I really don't know what equations would be relevant besides a proportion..
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!
