Desde el balcón de un edificio se deja caer una bola de boliche y llega a la planta baja en 5 s. a) ¿Con qué velocidad (en km/h) llega a la planta baja?

vf = Respuesta y unidad para la parte 1

b) ¿Desde qué altura se dejó caer la bola de boliche?

altura = Respuesta y unidad para la parte 2

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
