To what height should a block weighing 2 tons be lifted so that its potential energy

To what height should a block weighing 2 tons be lifted so that its potential energy increases from zero to 19.6 kJ

m = 2 t = 2000 kg.

g = 9.8 N / kg.

W0 = 0 J.

W = 19.6 kJ = 19600 J.

h0 = 0 m.

h -?

The potential energy of a block W of mass m, which was raised to a height h above the earth’s surface, is determined by the formula: W = m * g * h, where g is the acceleration of gravity.

Let us express the height of raising the block h above the earth’s surface by the formula: h = W / m * g.

h = 19600 J / 2000 kg * 9.8 N / kg = 1 m.

Answer: to increase the potential energy of the block, it must be raised to a height of h = 1 m above the earth’s surface.
