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 down an inclined plane. I have been working on this problem all day, and just seem to get myself more and more confused. Any help would be appreciated.
