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.

A rock is thrown from the edge of the top of a 5 m tall building at angle of 45° above the horizontal. The rock strikes the ground a horizontal distance of 8 m from the base of the building. Assume that the ground is level and that the side of the building is vertical. Determine the speed with which the rock was throw

A stone is dropped from a bridge. A second stone is thrown downwards 2.0 s later with an initial speed of 25 m/s. They both reach the water below at the same instant. (a) How long did it take for the first stone to reach the water? (b) How high is the bridge? (c) What are the speeds of the two stones just before they hit the water?

A 2 kg stone is dropped from a 50-m-tall building. Simultaneously, a second 1 kg stone is thrown horizontally from the building at a speed of 15 m/s, as shown in the figure. Calculate the x position of the center of mass of the two-stone system the moment after they are set in motion. Calculate the y position of the center of mass of the two-stone system the moment after they are set in motion. Calculate the x position of...

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
