In fact, the total energy of the rock when it <span>leaves the thrower's hand is the sum of the gravitational potential energy U and of the initial kinetic energy K:
</span>
<span>As the rock falls down, its height h from the ground decreases, eventually reaching zero just before hitting the ground. This means that U, the potential energy just before hitting the ground, is zero, and the total final energy is just kinetic energy:
</span>
<span>
But for the law of conservation of energy, the total final energy must be equal to the tinitial energy, so E is always the same. Therefore, the final kinetic energy must be

Cytokineses: the ending split of the cell membrane to create two identical cells
Answer:
Mars.
Explanation:
It only has a little over 24 hours in a day, its rotation axis is tilted about the same as earths, and I MAY actually have some water on its surface.(Though none has been discovered YET)
Hope this helps lots and lots,
sincerely, me
Answer:
D
Explanation:
The main reason for our large trade deficit is our relatively low rate of economic growth.
There are two main points that should be emphasized about the different types of electromagnetic radiation. The sequence from longest wavelength (radio waves) to shortest wavelength (gamma rays) is also a sequence in energy from lowest energy to highest energy
hope this helps you!✌
