Sometimes, because acceleration due to gravity on Earth depends on how close you are to the Earth's center.
The power delivered by the elevator is 34496 W.
<h3>What is power?</h3>
Power is the rate at which energy is used up.
To calculate the power delivered by the elevator, we use the formula below.
Formula:
- P = mgh/t.............. Equation 1
Where:
- P = Power delivered by the elevator
- m = Total mass on the elevator
- g = acceleration due to gravity
- h = Height
From the question,
Given:
- m = 1.1×10³ kg
- h = 40 m
- t = 12.5 s
- g = 9.8 m/s²
Substitute these values into equation 1
- P = 1.1×10³×40×9.8/12.5
- P = 34496 W.
Hence, the power delivered by the elevator is 34496 W.
