Question

488 J of work is done to a box which is moved across the floor for a distance of 8.9 m. What net force is required to act on the box to do this amount of work?

Answer 1

According to the formula
$a = f \times d$
Where a is work, f is force and d is the distance that box was moved over. And from that formula, you can get that f = a/d and that is 54.83N of force
