A 5.0 kg object is pushed across the floor and the attached force vs. displacement graph describes
the forces and displacement. What is the change in
KE of the object? (Hint: Net work = change in
kinetic energy)

none, its a machine

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.
