The boy would lose 25000 Joules going from the top of the hill to the village.

What is potential energy?

Potential energy is the energy stored in an object as a result of its position in relative with another object. It is given by:

Potential energy = mass * acceleration due to gravity (g) * height.

g = 10 m/s²

Let us assume the boy has a weight of 50 kg. His starting point is (400, -50) m. This means the hill is 50 m high and 400 m from the village.

Potential energy = 50 * 10 * 50 = 25000 Joules

The boy would lose 25000 Joules going from the top of the hill to the village.
