3. a block hangs from the ceiling by a massless rope. a second block is attached to
the first block and hangs below it on another rope. if each of the blocks has a
mass of 5.0 kg, what is the tension in each rope?

The first rope will have double the tension of the second rope down.

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.
