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 ?

A

ivory ball will rise to a greater height than wet clay ball.

B

ivory ball will rise to a lesser height than wet clay ball.

C

both balls will rise to the same height.

D

data is insufficient.

Text Solution

Verified by Experts

The correct Answer is:
A
As the ivory ball is more elastic than wet clay ball, therefore it will tend to regain its shape instantaneously after the collision: Hence, there will be a large energy and momentum transfer compared to the wet clay. Thus, the ivory ball will rise higher after the collision.

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

    A
    the ivory ball will bounce to greater height
    B
    the clay ball will bounce to a greater height
    C
    both the balls will bounce to the same height
    D

  • 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 :-

    A
    `5I_(1) = 6I_(2)`
    B
    `6I_(1) = 5I_(1)`
    C
    `I_(1) = 2I_(2)`
    D
    `2I_(1) = I_(2)`

  • 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 :-

    A
    `I_(2) = 2I_(1)`
    B
    `I_(2) = (I_(1))/(2)`
    C
    `I_(2) = 4I_(1)`
    D
    `I_(2) = (I_(1))/(4)`
