Two objects which have a total mass of 12.0 kg are placed adjacent to one another. the object on the left is 7.4 kg, and it pushed to the right with a force of 37 newtons. with what force does the left object push against the right object?

22.89 N

Explanation:

F = 37 N

Let the acceleration in the system is a and f be the force between the tewo blocks.

Apply the Newton's second law

By the free body diagrams

F - f = 7.4 x a .... (1)

f = 12 x a ...... (2)

Adding both of them

37 = 19.4 x a

a = 1.9 m/s^2

Put in equation (2)

f = 12 x 1.9 = 22.89 N

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.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
