In summary, the conversation was about a physics problem involving a box on an inclined ramp and determining the minimum force needed to keep the box at rest. The box has a mass of 22 kg and the ramp is at a 45 degree angle. The coefficients of friction were also given. The solution was to break the problem down into x and y components and to make sure the net force is equal to 0. The answer of 43 N was confirmed by another person.

So i did this question and got an answer of 43 N i was wondering if someone else could try it and tell me what they get.. it its not the same ill explain my steps and see where i went wrong.

Homework Statement


A box with a mass of 22 kg is at rest on a ramp inclined at 45 to the horizontal. The coefficients of friction between the box and the ramp are Us = 0.78 and Uk = 0.65.
Determine the magnitude of the smallest force that can be applied onto the top of the box, perpendicular to the ramp, if the box is to remain at rest.


Homework Equations


Fnet = 0
Ff = UFn

The Attempt at a Solution


I broke the question down into its x and y components.
