A body weighing 1 kg has a potential energy of 9.8 J. To what height is the body lifted?

m = 1 kg.
g = 9.8 m / s ^ 2.
Ep = 9.8 J.
h -?
The potential energy of the body En is determined by the formula: En = m * g * h, where m is the mass of the body, g is the acceleration of gravity, h is the height of the body above the earth’s surface.
h = En / m * g.
h = 9.8 J / 1 kg * 9.8 m / s ^ 2 = 1 m.
Answer: the body is raised to a height of h = 1 m above the ground.
