expresa en pocas palabras la utilidad que le darías al hecho de conocer los principios y leyes que rigen el moviento de los cuerpos

are there answer choices to this question? this seems like a question where you have options to choose from.

see earlier answer

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
