In the 121 m tall waterfall shown, Robinson climbs to the top, carrying his 71 kg body with him. If he then slides down, what should be his speed at the bottom? Would he be going faster if the waterfall was in one tier instead of two? (Ignore friction).

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.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
