Ask yourself: What would a $\Delta x > L/2$ mean for a particle confined to a box of width $L$?

I'm voting to close this question as off-topic because it shows no research effort.

comment Path integral (sum over paths where $v>c$)
The path integral is a formal integral over all paths in the mathematical sense. It is not an integral over "physical" paths, and the "reason" we integrate like that is simply that that is the correct integral to produce the quantities we want to compute, see any of the standard derivations of the path integral. I'm not sure what you're asking.

comment How to calculate impulse required to move an object vertically upward by given distance
Well, what you take as the duration of the momentary force really depends on what kind of force you're thinking about - I'm not sure how we can help here withoutfurther information.

comment Why an object with double length have the same friction?
Well, might you explain what exactly you didn't get about the highlighted part? Also, please include quotes as actual text, not as pictures.
