Physics

To solve this problem, we use the principles of conservation of momentum and conservation of kinetic energy since the collision is elastic.

 

Given:

Mass of object 1:

Mass of object 2:

Initial velocity of object 1:

Initial velocity of object 2:

Final velocity of object 1: (unknown)

Final velocity of object 2: (unknown)

 

Use the conservation of momentum.

The total momentum before the collision equals the total momentum after the collision:

 

Substitute the known values:

 

Use the conservation of kinetic energy.

The total kinetic energy before the collision equals the total kinetic energy after the collision:

 

Substitute the known values:

 

Solve the system of equations.

Now, we have two equations:

1.

2.
