You are pushing horizontally on a couch with a force of 60N, but it's not moving. A) How much friction is present at that moment? You push hard until is start moving. After it is moving across the floor you are pushing it so it is going at a constant velocity of 0.25 m/s. B) If you pushing with a force of 140 N, how much friction force is there between the floor and the couch resisting the motion at that time?

    Rachel is pushing a box across the floor while Jon, at the same time, is hoping to stop the box by pushing in the opposite direction. There is friction between the box and floor but you may ignore the effect of air resistance. Draw the force diagram for the box's motion and then choose the appropriate forces from the following list that should be included on the force diagram. Assume that the box is moving to the right during the...

    While moving in, a new homeowner is pushing a box across the floor at a constant velocity. The coefficient of kinetic friction between the box and the floor is 0.423. The pushing force is directed downward at an angle θ below the horizontal. When θ is greater than a certain value, it is not possible to move the box, no matter how large the pushing force is. Find that value of θ.
