The body is pulled horizontally and evenly with a force of 10 N over the surface with a friction coefficient of 0.25. Determine your body weight.

Initial data: F – force applied to the body being moved (F = 10 N); a (acceleration with uniform motion) = 0 m / s2; μ (coefficient of friction) = 0.25.

Constants: by condition g (acceleration of gravity) = 10 m / s2.

To find the mass of the body being moved, we project all the forces onto the horizontal axis: m * a = 0 = F – Ftr = F – μ * m * g, whence we express: m = F / (μ * g).

Calculation: m = 10 / (0.25 * 10) = 4 kg.

Answer: The body being moved has a mass of 4 kg.
