1. A ball bouncing against the ground and rebounding is an example of an elastic collision. Describe two different methods of evaluating this interaction, one for which momentum is conserved, and one for which momentum is not conserved. Explain your answer.

One method to solve this problem is to take the ball and the floor as the system

second method to solve this exercise and we take the system as formed by the ball only

Explanation:

One method to solve this problem is to take the ball and the floor as the system, therefore the forces that occur during the collision are driving force and reaction, internal to the system, therefore the moment is conserved.

A second method to solve this exercise and we take the system as formed by the ball only, in this case there is a change at the moment and this is not preserved, This second case is a little more difficult to solve
