EasyTwo identical solid balls,one of ivory and the other of wet-clay,are dropped from the same height on the floor. Which one will rise to a greater height after striking the floor and why?
(A) The ivory ball is more elastic than the wet-clay ball.
When the ivory ball strikes the floor,it undergoes elastic deformation and quickly regains its original shape,storing potential energy that helps it rebound.
In contrast,the wet-clay ball is highly plastic; it undergoes permanent deformation upon impact and absorbs most of the kinetic energy,resulting in little to no rebound.
Therefore,the ivory ball will rise to a greater height after striking the floor.
