```							Dear Aviral The velocity of ball just before hitting the floor is sqrt(2gh) and its kinetic energy will be 1/2mu^2=mgh.after hitting it loses 60% of its energy or we say it possess only 40% of its initial energy .its energy after hitting the floor is 40/100(mgh)after reaching its maximum height h' it will lose all its kinetic energy and will possess only potential energy which is mgh'.therefore law of conservation of energy says that mgh'=40/100(mgh)h'=0.4h RegardsArun (askIITians forum expert)
