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. 12,500 J C. 5 N D. 12,500 N
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.
Joules are not part of the answers because your force is newtons and then you multiply that by the distance that the force was applied. So D is the answer...
Required formula is W=F*d=250*50 Joule=?
the unit of work is joules.. newton is the unit of force..so eliminate c and d.. now work=f*d =250*50=12500j option b
