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
