An elevator has 750,000 J when it is lived 500 meters in the air
Answer: Option D
Explanation:
The expression to find the potential energy completely on the basis of forces that on two objects. It can be written as
[tex]potential\ energy (P . E)=m \times acceleration\ due\ to\ gravity\ (g) \times height (h)[/tex]
Where,
m – mass of object
Acceleration due to gravity = [tex]9.8 \mathrm{m} / \mathrm{s}^{2}[/tex]
h = 500 meters
Force = 1500 Newton
As we know, according to Newton second law of motion, the force can be expressed in terms of mass and gravity (F= ma). So, the potential energy can be calculated as
[tex]P . E=F \times h=1500(500)=750000 J[/tex]
Hence, an elevator has 750,000 J when it is lived 500 meters in the air.
