Answer:
<em>W=700 Joule</em>
Explanation:
<u>Physics Work
</u>
Is the dot product of the force vector by the displacement vector
![W=\vec F \cdot \vec r](https://tex.z-dn.net/?f=W%3D%5Cvec%20F%20%5Ccdot%20%5Cvec%20r)
When both the force and the displacements are pointed in the same direction, the formula reduces to its scalar version
![W=F.d](https://tex.z-dn.net/?f=W%3DF.d)
The weightlifter is applying a net force of 350 N to lift the weights a distance of 2 m, thus the net work done is
![W=350\ N\ .\ 2\ m=700\ Joule](https://tex.z-dn.net/?f=W%3D350%5C%20N%5C%20.%5C%202%5C%20m%3D700%5C%20Joule)
I think Dwarfs, but I’m not positive
