Answer:
1000 J is done when a force of 50 N is used to drag an object a distance of 20 meters across a floor. work = force x distance W = 50N * 20 meters W = 1000 J

Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d).
120 = 30m x60
120 = 1800
