Physics

To find the average force exerted by the 1 kg ball on the 3 kg ball during the collision, we can use the following relationship:

 

Where:

is the average force,

is the change in momentum of the 3 kg ball,

is the duration of the collision.

 

Calculate the change in momentum of the 3 kg ball

According to Momentum and Kinetic Energy Conservation, we have

 

We can solve:

 

Where:

is the mass of the 1 kg ball,

is the mass of the 3 kg ball,

is the initial velocity of the 1 kg ball,

is the initial velocity of the 3 kg ball.

 

Substituting values into the equation:
