| **The sled moves from its place if a horizontal force of 60 N is applied to them, what is the mass of the sled if the friction force is 0.03 of their weight.**

Data: F (horizontal force applied to the given sled) = 60 N; Ftr = 0.03Р (sleigh weight).

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

To find the mass of the given sleigh, we use the equality: F = Ftr. = 0.03Р = 0.03 * m * g, whence m = F / (0.03 * g).

Calculation: m = 60 / (0.03 * 10) = 200 kg.

Answer: The given sleds have a mass of 200 kg.
