Answer:
207 W
Explanation:
I assumed here that the object is moved vertically. If that is the case, the work done on the object is equal to its change in gravitational potential energy:
[tex]W=\Delta U = mg \Delta h[/tex]
where
m = 47 kg is the mass of the object
g = 9.8 m/s^2 is the acceleration of gravity
[tex]\Delta h = 27 m[/tex] is the change in height
Substituting,
[tex]W=(47)(9.8)(27)=12436 J[/tex]
Now we can calculate the power used, which is given by
[tex]P=\frac{W}{t}[/tex]
where t = 60 s is the time taken. Substituting,
[tex]P=\frac{12436}{60}=207 W[/tex]
