1. The problem statement, all variables and given/known data A hollow spherical shell is rolling without slipping or sliding down a board that is tilted at an angle of 35.0° with respect to the horizontal. What is its acceleration? 2. Relevant equations I=2/3mr^2 if an object rolls without slipping or sliding: v = rw that means that a = r*alpha right? 3. The attempt at a solution I imagine the solution would be something times g sin(35) but I am not sure exactly how to go about solving this one.
