A student with mass 47.0 kg jumps off a high diving board.
Using 6.00×1024 kg for the mass of the earth, what is the acceleration of the earth toward her as she accelerates toward the earth with an acceleration of 9.80 m/s^2? Assume that the net force on the earth is the force of gravity she exerts on it.

Best answer gets 10pts.

Ok, I know this sounds wierd, but if I hadn't seen it, I would have never believed it. My neighbor was having a trench dug to install piping. When the contractors came out, the nieghbor said, "Due to last night's phase of the moon, you will not be able to fill the hole/trench." This applied to the trench and the hole that was dug.

Everyone grinned and went to work. However, when the contractors tried to fill the hole with the dirt they removed, they could not. In addition, they had to bring dirt to the site to fill up the hole.

So, have any of you ever heard this? And why was the amount of dirt removed not able to fill the hole and trench that were dug.

I realize that the conglomeration/accumulation of matter is what propels the spin of stars and planets. First of all, is everything in the Milky Way spinning the same direction? If the Milky Way came into existence first with its' counter-clockwise spin, would that give the stars in the galaxy a predisposition to spin counter-clockwise thus adding another factor to the direction and velocity of stellar and planetary spin?
