Physics

We are given the velocities of the objects after the collision, so we can use them to find the total kinetic energy after the collision.

 

Calculate the total kinetic energy after the collision

 

The kinetic energy of an object is given by the formula:

 

Where:

is the mass of the object,

is the velocity of the object.

 

For the 0.25 kg ball:

 

For the 1.25 kg ball:
