The forklift exerts a 1500 N force on the box and moves it 3 M forward to the stack how much work does the forklift do

If the force is applied to lift the box, then there is no work done as the displacement of the box is not in the same direction of the box.

However, if the force is being applied to move the box in the direction of the force, then the work done is:

Work = force x distance

Work = 1500 x 3

Work = 4,500 Joules
