The power produced is 712.5 W
Explanation:
First of all, we start by finding the work done by the forklift.
The work done on an object pushed in the same direction as the force is given by:
[tex]W=Fd[/tex]
where
F is the magnitude of the force
d is the displacement of the object
In this problem,
F = 475 N is the force applied to raise the box
d = 18 m is the displacement
Substituting,
[tex]W=(475)(18)=8550 J[/tex]
Now we can calculate the power, which is the ratio between the work done and the time taken:
[tex]P=\frac{W}{t}[/tex]
Here we have,
W = 8550 J
t = 12 s
Substituting,
[tex]P=\frac{8550}{12}=712.5 W[/tex]
