To what height can a body weighing 5 kg be lifted by performing a mechanical work of 10 J.

m = 5 kg.
g = 9.8 m / s ^ 2.
A = 10 J.
h -?
Mechanical work is determined by the formula A = m * g * h, where m is the mass of the body that is being lifted, g is the acceleration of gravity, h is the height of the body being lifted.
h = A / m * g.
h = 10 J / 5 kg * 9.8 m / s ^ 2 = 0.2 m.
Answer: the body can be raised to a height of h = 0.2 m.
