An airplane is cruising along at a constant velocity of 245m/s East. Amazing Austin is on this airplane and wants to build a roller coaster out of the friction-less knex toys he brought. He builds a hill that is 1.5m high and then a loop to loop that is .7m high. He puts the .25kg cart at the top of the hill and enjoys the roller coaster.

How much energy did the cart have at the top of the hill and at the top of the loop to loop?

I hope that rollercoaster isn't in the plane's path or it won't be cruising at a constant velocity of 245m/s for long.

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.
