Two idential solid balls, one of ivory and the other of wet caly, are dropped from the same height on the floor. Which one will rise to a greater height after striking the floor and why ?

Two smilar balls, one of which is made of ivory while the other of clay, are dropped from the same hight, then

Two balls of different masses (one lightre an other heavier) are thrown vertically upward with same initial speed. Which one will rise to greater height ?

Two bodies, one of mass 1 gram and other of mass 1 kiliogram are dropped are dropped from the same height.which one will hit the ground first ?

Two balls of same mass are dropped from the same height h, on to the floor. The first ball bounces to a height h//4 , after the collision & the second ball to a height h//6 . The impulse applied by the first & second ball on the floor are I_(1) and I_(2) respectively. Then :-

Two balls of same mass are dropped from the same height h, on to the floor. The first ball bounces to a height h/4, after the collision & the second ball to a height h/16. The impulse applied by the first & second ball on the floor are I_(1) and I_(2) respectively. Then

Two balls of same mass are dropped from the same height onto the floor. The first ball bounces upwards from the floor elastically. The second ball stricks to the floor. The first applies an impulse to the floor of I_(1) and the second applies an imupulse I_(2) . The impulses obey :-
