wedge

any hints??

yaar analyse the motion
as the ring rolls down the wedge will move backwards
now there is friction between ring and the surface so show the force
draw FBD.....
u have to derive the results here
no standard formula will be used as the wedge is moving backwards

tried solving using energy but didn't get the answer.can u pls try

yaar energy mere khyaal se nahin lag sdakta
friction baba hain na
and remember that the wedge is also remember
