| **What is the minimum work done by the force when moving a body with a mass of m = 10kg along a horizontal plane at a distance of S = 50m? The coefficient of friction between the body and the plane is 0.5.**

Task data: m (mass of the body being moved) = 10 kg; the body moved along a horizontal plane; S (required distance) = 50 m; μ (coefficient of friction between the body and the horizontal plane) = 0.5.

Reference values: g (acceleration due to gravity) ≈ 10 m / s2.

The minimum work force when moving the body can be calculated by the formula: A = F * S = Ftr. * S = μ * N * S = μ * m * g * S.

Calculation: A = 0.5 * 10 * 10 * 50 = 2500 J (2.5 kJ).

Answer: The minimum work will be 2.5 kJ.
