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]
