Question

Локомотив мощностью 600 Вт,двигаясь равномерно,проходит за 20 с 200 м.Какова его сила тяги?

Answer 1

скорость локомотива v=200/20=10 м/с

тогда сила тяги F=P/v=600/10=60 Н

Answer 2

Calculation of the Tractive Force

To calculate the tractive force of a locomotive, we can use the formula:

Tractive Force (F) = Power (P) / Velocity (v)

Given that the locomotive has a power of 600 W and travels a distance of 200 m in 20 s, we can calculate the velocity using the formula:

Velocity (v) = Distance (d) / Time (t)

Substituting the values, we have:

Velocity (v) = 200 m / 20 s = 10 m/s

Now we can calculate the tractive force:

Tractive Force (F) = 600 W / 10 m/s = 60 N

Therefore, the tractive force of the locomotive is 60 N.
