a metal crate with a mass of 500 kg is pushed across a metal floor for 5 minutes.50N is applied horizontally.box does not move, extra 50 N is applied.after 2 minutes then box moves 4meters,how much work is done
Answered by Damon
no work is done until the box moves.

W = F * d

W = 100 N * 4 meters = 400 Joules

Most of this question is added nonsense intended to confuse you.

We push a large box for three minutes. During that time, we exert a constant force of 200N on the box, but it does not move. How much work has been accomplished?
Answered by Damon
NONE !!
Force times distance moved in the direction of the force !!!!!
