There exists a spherical planet about the size of the Earth with a uniform density of 5000 kg/m³. A hole (negligible mass removed) is drilled through the diameter of the planet so that objects can be dropped and freely fall. A bowling ball is lowered into the hole to a height of 1,000,000 m above the center of the planet where it is released from rest. How far away is the ball from where it was released after 3 hours? (Assume the planet is completely at rest.)

Aha, you posted the answer xD God dam man, that shit was long. Are you in college? if so, what are you majoring in?

Not yet. I'm a senior in HS.
