Answer:
W = 3F
Step-by-step explanation:
Work is defined as the inner product between force and displacement. The inner product picks out the force components which point in the same direction as the displacement. The vertical components do not matter in the horizontal displacement. I am assuming you're dealing with 1-dimensional motion? Then the work would be:
The displacement is 3 meters. Therefore, the work is:
You haven't gave the force being applied to the object, so I cannot give an explicit answer. Just multiply the force by 3 to get the work.
