Three identical 6.0-kg cubes are placed on a horizontal frictionless surface in contact with one another. the cubes are lined up from left to right and a force is applied to the left side of the left cube causing all three cubes to accelerate to the right at 2.0 m/s2 . what is the magnitude of the force exerted on the middle cube by the left cube in this case?

24 N

Explanation:

= mass of the cube =

Consider the three cubes together as one.

= mass of the three cubes together =

= acceleration of the combination = 2 ms⁻²

= Force applied on the combination

Using Newton's second law

= Force by the left cube on the middle cube

Consider the forces acting on left cube, from the force diagram, we have

electrical power

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.
