Answer:
1863 J
Explanation:
F = Force moving the object
f = Frictional force = 230 N
The forces in the horizontal direction have the force balance
[tex]F-f=0\\\Rightarrow F=f\\\Rightarrow F=230\ \text{N}[/tex]
So, the force by which the object is being pushed is [tex]230\ \text{N}[/tex]
s = The displacement of the object = 8.1 m
Work done is given by
[tex]W=Fs\\\Rightarrow W=230\times 8.1\\\Rightarrow W=1863\ \text{J}[/tex]
The work done by the mover is 1863 J.
