Answer:
43,555 W
Step-by-step explanation:
Since the speed is constant, this means that the force applied to lift the equipment is equal to the weight of the equipment. So we can write:

where
m = 1000 kg is the mass
is the acceleration due to gravity
So,

Then the work done in lifting the equipment is:

where
d = 200 m is the displacement of the equpment
Substituting,

Finally, the power used to lift the equipment is the ratio between the work done and time taken:

where

t = 45 s is the time taken
Solving,
