Answer:

W=700 Joule

Explanation:

Physics Work

Is the dot product of the force vector by the displacement vector

[tex]W=\vec F \cdot \vec r[/tex]

When both the force and the displacements are pointed in the same direction, the formula reduces to its scalar version

[tex]W=F.d[/tex]

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

[tex]W=350\ N\ .\ 2\ m=700\ Joule[/tex]
