A problem on rotational mechanics

[nikhilnagaraj]

Homework Statement

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)

Homework Equations

I GUESS,
L =Iw , K=.5 Iw^2 , I.is moment of inertia.

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...
