A boy carries a 50 N box up a flight of stairs 10-m high. How much potential energy has the box gained?

Respuesta :

Answer:

Potential energy, P = 500 J

Explanation:

We have,

Weight of the box, W = 50 N

Height of the stairs, h = 10 m

It is required to find the potential energy gained by the box. The potential energy is possessed by an object due to its height. The formula of potential energy is given by :

[tex]P=mgh[/tex]

g is acceleration due to gravity

[tex]P=50\ N\times 10\ m\\\\P=500\ J[/tex]

So, the potential energy of 500 J is gained by the box.
