The mass of the (elevator + person) is (2,000 kg + 60 kg) = 2,060 kg .
The weight is (mass x gravity) = (2,060 x 10) = 20,600 newtons
Work = (force x distance) = (20,600 newtons x 24m) = <em>494,400 joules</em>
The speed, acceleration, and how much time it takes don't make any
difference, unless you want the average power during the lift.
Power = (work)/(time) =
494,000 J / (24/4 m) =
494,000 J / 6 sec = <em><u>82,400 watts</u></em> wow !

Hope this helps Have a good day
Answer:
Measurement is important so we could measure certain things right. By taking measurements we can have a knowledge of sizes, lengths, widths etc.
Explanation:
No air conditioning, I already don’t have it, I only have heating :(
