Use the work–energy theorem to solve each of these problems. Then use Newton’s laws to check your answers. Neglect air resistanc
e in all cases. (a) A branch falls from the top of a 95.0- m-tall redwood tree, starting from rest. How fast is it moving when it reaches the ground? (b) A volcano ejects a boulder directly upward 525 m into the air. How fast was the boulder moving just as it left the volcano?
The earth obviously because it is on Earth like we are and it has the same gravital properties. It falls when you drop it and rises when you pick it up
The best position for the person would be outside, under a clear sky, standing up. He should do it sometime between sunset and sunrise, from a day before until a day after the moment of Full Moon.
The Specific Heat Capacity of silver is 230 J/kgK, melting point is 961.8 C so the difference is 941.8K. Now we simply do q=230J/kgK*16.5kg*941.8K and that is 3 574 131 J
