Explanation:
Let [tex]W[/tex] be the work done.
Let [tex]F[/tex] be the force applied.
Let [tex]S[/tex] be the displacement of the object.
Workdone by a object is defined as the dot product of force and displacement.
[tex]W=F.S[/tex]
Given,[tex]F=600N[/tex]
[tex]S=2m[/tex]
So,
[tex]W=F.S=600\times 2=1200joules[/tex]
So,workdone by Steve is [tex]1200[/tex] joules.
