What is the change in momentum of a 13 kg object accelerating from 20 m/s to 12 m/s?

false

explanation:

boats, things on boats luggage are way more heavy then water.

b.

hope this : )

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.
