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

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
