Static Friction Between a Box and the Floor

[QUOTE="jbriggs444, post: 6834575, member: 422467"] Ideally, if the applied force is being ramped up slowly, it will only be equal to static friction for an instant. Prior to that and it is less than static friction. More than that and the object moves and it cannot be static friction any longer. Practically, things are not quite as clean as this. The dividing line between static and kinetic friction is not always sharp. Some times one gets things like chattering and squeaking. Also, no experiment is perfect. [USER=602748]@hmmm27[/USER] has it right. The question says that it moves. If you have to pretend that this takes 35.000001 N then go ahead and pretend that 35.000001 N was applied. It won't affect your results which are only good to two significant figures anyway. [/QUOTE]
