You are pushing a wooden crate across the floor at a constant speed. You decide to turn the crate on end, reducing by half the surface area in contact with the floor. In new orientation, to push the same crate across the same floor with the same speed, the force that you apply must be about: A) four times as great B) twice as great C) equally great D) half as great E) one fourth as great
I'm pretty sure surface area does not relate to the force needed; as friction equations don't account for surface area just mass. But otherwise, I'm really not sure, and there must be more reason to it than that the simple Newton's laws equations not accounting for surface area...
