Question

you must exert a force of 4.5 N on a book to slide it across a table. If you do 2.7 j of work in the process, how far have you moved the book?

Answer 1

Work = (force) x (distance)

2.7 Joules = (4.5 N) x (distance)

distance = 2.7 J / 4.5 N

= 0.6 meter

Answer 2

Work done (energy) = force * distance

So: distance = work done / force

= 2.7 / 4.5

= 0.6m
