Suppose work input is 25 j , and the output distance 10 m . factoring in the effect of friction which must be true about output force

Work is defined as the product of force times the distance. Taking in the effect of friction, the equation of input work will look like this:

input work = work against friction + output work
25 = |w| + 10F

Considering that friction exists, then |w| > 0:

25 - 10F > 0

Therefore:
F < 2.5 N

Simple, don't do it. just don't go to that dock
