Durante una tempestad, se escucha un trueno 8s despues de haber percibir el relámpago. ¿A que distancia cayo el rayo ? ( v= 340 m/s) doy 10 puntos

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

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.
