what horizontal force has to be applied to a wheely bin if it is to be wheeled to the street on a horizontal path against a frictional force of 20N at a constant 1.5m s-¹ ?

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.

i would say
