Question

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

Answer 1

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
