Question

An elevator weighs 1500 Newtons. Calculate how much potential energy it has when it is lived 500 meters in the air.


75,000 J


750 J


7,500,000 J


750,000 J

Answer 1

Answer:

750,000 J

Explanation:

Given:

Force applied on the elevator (F) = 1500 N

Height or displacement of the elevator (h) = 500 m

Now, potential energy is the energy stored due to the work done on it by the force causing the displacement 'h'.

So, work done by the force 'F' is given as:

Work = Force(F) × Displacement(h)

Work = 1500 × 500 = 750,000 J

Therefore, potential energy stored in the elevator is equal to the work done by the force 'F'. So,

Potential Energy = Work done

Potential Energy = 750,000 J
