Determine the work done with a uniform sliding of a sled weighing 20 kg over the snow while moving them 10 m

Determine the work done with a uniform sliding of a sled weighing 20 kg over the snow while moving them 10 m, the friction force of the carts on the snow is 0.02 of the weight of the sled.

These tasks: m (the mass of the sled under consideration) = 20 kg; S (sled movement) = 10 m; Ftr (friction force of runners on snow) = 0.02P; the movement of the sleigh is uniform (F = Ftr).

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

To determine the work that was done during the movement of the sled, we use the formula: A = F * S = Ftr * S = 0.02P * S = 0.02 * m * g * S.

Let’s perform the calculation: A = 0.02 * 20 * 10 * 10 = 40 J.

Answer: With uniform sliding of the sled, a work of 40 J.
