Question

Problem 26

Answer 1

Given information

We are given that;

The first hockey puck's mass,  
Initial velocity of the first hockey puck,    
The second hockey puck's mass,  
Initial velocity of the second hockey puck,    

 

Step-by-step explanation

Step 1.

It is the case of elastic collision, hence momentum will be conserved which can be depicted as, 

.  

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,

.
