Question

Problem 25

Answer 1

Given information

Information given in the question:-

The first ball velocity,  
The first ball's mass, .
Final velocity of the second ball,  

The second ball's mass,  

 

Step-by-step explanation

Step 1.

According to the law of conservation of momentum, the pre-collision impulse is the same as the post-collision impulse of an elastic collision.

 

According to the law conservation of energy, the potential energy before the collision is the same as the potential energy after the collision of the elastic collision and it is given by,

 

Where,

The final velocity of the first ball is .

The final velocity of the second ball is .
