An object whose mass is 100 kg is located 20 m above a datum level in a location where standard gravitational acceleration exists. Determine the total potential energy, in kJ, of this object.

Respuesta :

Answer:19.6 kJ

Explanation:

Given

mass of object [tex]m=100\ kg[/tex]

Object is at a height of [tex]h=20\ m[/tex]

Potential energy of an object depends upon datum . so Potential energy of object is

[tex]P.E.=mgh[/tex]

[tex]P.E.=100\times 9.8\times 20[/tex]

[tex]P.E.=19.6\ kJ[/tex]
