So that means: Fsubf = 24.5 24.5 = mu x W x cosTheta 24.5/(mu x cosTheta) = W Thank you so much, I did not recall that relationship between the Friction force and muN.

I have :(. I don't know the weight, only what I gave above. It seems to me like I need one more piece of information, such as the weight. That is why I posted here, to see if I was missing something obvious.

I can't figure out how to get the mass of this object, with the information given: Inclined plane with angle relative to the ground of 20 degrees. It takes 70 Newtons to get the object moving up the plane. "Mu" of static friction: 0.35 All my example problems involve an object going...
