Answer:
234 J
Explanation:
Assuming that the force applied by Zak is in the same direction of the displacement of the sofa, the work done by Zak is given by
[tex]W=Fd[/tex]
where
F = 36 N is the force applied by Zak
d = 6.5 m is the displacement of the sofa
Substituting these numbers into the equation, we find the work done by Zak:
[tex]W=(36 N)(6.5 m)=234 J[/tex]
