1. The problem statement, all variables and given/known data A uniform solid sphere of radius R rolling on a rough horizontal surface without slipping, with an angular velocity 'w' meets a rough inclined plane of inclination 60degrees. The sphere continues to roll up the plane without slipping with an angular velocity 'n' given by ______________ (in terms of w) (Please refer the attachment for the diagram) 2. Relevant equations I GUESS, L =Iw , K=.5 Iw^2 , I.is moment of inertia. 3. The attempt at a solution I think this problem requires Conservation of angular momentum , but I do not know how to start or where to apply the principle.
