Question

How much work is accomplished when a force of 250 N pushes a box across the floor for a distance of 50 meters?
A) 5 J
B) 5 N
C) 12,500 N
D) 12,500 J

Answer 1

the first thing you should realize here is what the units of work are.
Work is equal to Force*Distance. You are given a force and you are given a distance. Dimensionally speaking it wouldn't make any since for the answer to have nothing but units of Newtons so that takes out two of your choices right there.

Answer 2

\[w=f*x\]

Answer 3

for the peeps who need it, it's D

Answer 4
