While moving a 13 kg refrigerator, an upward force of 28 n is applied 52 degrees above the horizontal, so that it accelerates from rest at 1.2 m/s2. what is the frictional force between the refrigerator and the floor?

the frictional force is 1,63 N

Explanation:

We use the second law of movement proposed by Newton and with the help of a free body diagram, we can get the equations for the solution.

In the image attached, we can see a completely analysis of the refrigerator under the different forces and the equations. We must understand the relationship between the normal force and the kinetic friction coefficient.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
