A horizontal force causes an item weighing 10 kg to accelerate at 5 ms2, moving it 20 meters in a horizontal direction. How much labor does the force perform?
The force's magnitude is determined by 
F=ma=(10)(5)=50N 
It acts over a 20-meter distance in the same direction as the object's displacement, indicating that the force's total work is provided by
W=Fx=(50)(20)=1000 Joules
