Starting at rest, a 5.4 kg tree branch falls and hits the ground at a speed of 41 m/s. What was the GPE of the tree branch before it fell? Ignore the air resistance.

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
