A rock is dropped from the top of a tall tower. Half a second later another rock, twice as massive as the first, is dropped. Ignoring air resistance,

		they strike the ground with the same kinetic energy
		they strike the ground more than half a second apart.
		the distance between the rocks increases while both are falling.
		the acceleration is greater for the more massive rock.

Galileo's great-great-great grandchild stands at the top of a vertical tower 57.8 m tall with a Chianti bottle. How long does it take for the bottle to fall to the ground, if it was just dropped from the tower? How far does the bottle land from a point on the ground directly beneath the point from which it was launched, if the bottle was thrown straight out horizontally from the tower with a speed of 12.9 m/s? What is the...

A quarter is dropped from rest from the fifth floor of a very tall building. The speed of the quarter is v just before striking the ground. From what floor would the quarter have to be dropped from rest for the speed just before striking the ground to be approximately 2v? Assume equally spaced floors and ignore all air resistance effects to determine your answer. please focus on showing the process to achieve the answer, thank you
