1. A 1000 kg equipment lift travels up a 200 m shaft in 45 seconds. Assuming the speed is constant, what is the
average power?

43,555 W

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,

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
