Homework Help: A problem on rotational mechanics

  1. Apr 25, 2014 #1
    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.

    Welcome to the PF.

    Try using conservation of energy instead... :smile:
