Dear Aveek


let the initial velocity of sphere is U


case 1 :  sphere is rolling


 acceleration along the inclind plane a= gsinθ/[1+ I/mr2]


I = 2/5 mr2


so a = 5/7 gsinθ


 now equation  V2 =U2- 2aS


  S=U2/2a


 so  h2 =S sinθ = 0.7 U2/2g


 case 2:  sphere is not rolling


  a =gsinθ


and h1=Ssinθ = 0.5U2/2g


h2 > h1
