Determine the mass of the brick pallet, which, at a height of h = 10m relative to the Earth’s surface, has a potential energy equal in magnitude to the energy released during the complete combustion of gunpowder with a mass of m ‘= 10g.

Task data: h (height at which the brick pallet is located) = 10 m; m2 (mass of burnt powder) = 10 g (in SI m2 = 0.01 kg).

Reference values: q (specific heat of combustion of gunpowder) = 0.38 * 10 ^ 7 J / kg; g (acceleration due to gravity) ≈ 10 m / s2.

The mass of a brick pallet can be expressed from the equality: m1 * g * h = q * m2, whence m1 = q * m2 / (g * h).

Let’s calculate: m1 = 0.38 * 10 ^ 7 * 0.01 / (10 * 10) = 380 kg.

Answer: The mass of a pallet of bricks is 380 kilograms.
