Amodel rocket with a mass of 0.181 kg is launched into the air with an initial speed of 92 m/s. how much kinetic energy will the rocket have at a height of 164 m? assume there is no wind resistance.
303 j - 747 j - 634 j - 444 j
i have tried taking the initial ke with 1/2*.181*92^2 and subtracted the final potential energy .181*9.8*164. this gets me 475, which isn't any of the choices. i picked 444 j since it was the closest, but it was wrong.

c. magnitude and direction

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.
