Question

Коэффициент трения полозьев санок о снег равен 0,2. Какую силу должен приложить мальчик, чтобы равномерно тянуть санки, если их масса 48 кг.

Answer 1

F тр= mmg= 0,2x10x48 =96 ньютон

Answer 2

Calculating the Force Required to Pull the Sled

To calculate the force required to pull the sled, we can use the formula:

Force = Coefficient of Friction × Weight

Given: - Coefficient of friction (μ) = 0.2 - Weight of the sled (m) = 48 kg

Calculation

Using the formula, the force required to pull the sled can be calculated as follows:

Force = 0.2 × 48 kg

Result

Force = 9.6 kg

Therefore, the force required to pull the sled evenly is 9.6 kg.
